Yanis Benane 4 ABSTRACT Ultrasound imaging is a diagnostic tool widely used thanks to such virtues as real-time data acquisition / processing, ease of use and safety for the patient / practitioner during examination. However, when compared to other imaging methods such as X-ray tomography and Magnetic Resonance Imaging, the echography has the disadvantage to provide relatively low image quality. In this thesis, a method that is able to increase the ultrasound image quality, thus paving the way towards improved diagnostics based on echography and novel ultrasound applications, is studied. In order to increase the echo signal to noise ratio of the received signals, linear frequency modulated signals (also called chirps) are proposed. To avoid the negative effect of the bandlimited acquisition probe, a pre- enhancement step is applied on the probe excitation signals, in order to boost the signal energy in the frequency bands where the probe is less efficient. Wiener filters that allow obtaining a good trade-off between the spatial resolution and noise stability are used to compress the echo energy. The previously detailed pipeline (also called REC: Resolution Enhancement Technique) is applied on ultrafast imaging schemes. Promising results in simulation and in-vitro, ex-vivo, in-vivo acquisitions are shown. Furthermore, REC was adapted in such way that the frequency dependent tissue attenuation effect is compensated for. This improvement is validated in simulation and phantom experiments. REC was also adapted to the nonlinear propagation of ultrasound waves, by proposing a pulse inversion technique that uses REC to provide a better image resolution and contrast to noise ratio. Then, the generality of the REC method was demonstrated by applying it to different acquisition schemes such as diverging wave compounding and Multi Line Transmit (MLT). We also show that the image quality can be increased more by taking into account the spatial impulse response of the ultrasound probe when REC and MLT are combined. The last contribution of this thesis consists on combining orthogonal binary codes with REC pre-enhanced chirps in order to boost further the eSNR provided by REC while keeping its good performance in axial resolution. The method is applied to diverging wave compounding. Pairs of diverging waves are transmitted/received/reconstructed simultaneously thanks to the orthogonality property of the Golay codes. The results show that the proposed method is able to obtain a better image quality than conventional pulse imaging. Yanis Benane 5 CONTENTS 1.

  • Optimization of Short Probe Linear Frequency Modulated Signal Parameters
    ARCHIVES OF ACOUSTICS DOI: 10.2478/v10168-011-0057-1 36, 4, 861–871 (2011) Optimization of Short Probe Linear Frequency Modulated Signal Parameters Włodzimierz POGRIBNY(1),(2), Tadeusz LESZCZYŃSKI(1) (1)University of Technology and Life Sciences Kaliskiego 7, 85-796 Bydgoszcz, Poland e-mail: pohry, leszcz @utp.edu.pl { } (2)University of Economy in Bydgoszcz Garbary 2, 85-229 Bydgoszcz, Poland (received June 17, 2011; accepted October 20, 2011 ) In many physical experiments, linear frequency modulated (LFM) signals are widely used to probe objects in different environments, from outer-space to under- water. These signals allow a significant improvement in measurement resolution, even when the observation distance is great. For example, using LFM probe sig- nals in underwater investigations enables discovery of even small objects covered by bottom sediments. Recognition of LFM (chirp) signals depends on their compression based on matched filtering. This work presents two simple solutions to improve the reso- lution of the short chirp signals recognition. These methods are effective only if synchronization between the signal and matched filter (MF) is obtained. This work describes both the aforementioned methods and a method of minimizing the effects of the lack of synchronization. The proposed matched filtering method, with the use of n parallel MFs and other techniques, allows only one sample to be obtained in the main lobe and to accurately locate its position in the appropriate sampling period Ts with accuracy Ts/n. These approaches are appropriate for use in probe signal processing. Keywords: sonar, LFM signal, matched filtering. 1. Introduction For many physical investigations, short chirp signals are especially expedi- ent because they enable the probe rate to be increased (Grelowska, Koza- czka, 2010; Mahafza, Elsherbeni, 2004; Pogribny et al., 2002; Schock, LeBlanc, 1990).

Wiesbeck Marwan Younis Digital Beam-Forming for High Resolution Wide Swath Real and Synthetic Aperture Radar Band 42 Copyright: Institut für Höchstfrequenztechnik und Elektronik Universität Karlsruhe (TH) alle Rechte vorbehalten Druck: Druckerei Gunter Dünnbier, 02779 Großschönau, Tel. 035841-36757 ISSN: 0942-2935 Forschungsberichte aus dem Institut für Höchstfrequenztechnik und Elektronik der Universität Karlsruhe (TH) Vorwort des Herausgebers Als Anfang der 60-iger Jahre die vorteilhafte Nutzung der digitalen Technik gegenüber der analogen Technik in vielen Bereichen erkennbar wurde, waren die meisten der analogen Technik nahe stehenden Ingenieuren und Wissenschaftler verunsichert. Es wurden Fronten aufgebaut und in zahlreichen Publikationen nachgewiesen, warum die digitale Technik nicht leistungsfähig ist. Diese Einstellungen gehören zwischenzeitlich der Vergangenheit an. Die nachkommenden Generationen an Ingenieuren und Wissenschaftlern standen digitalen Problemlösungen offener gegenüber. Heute hat die Digitaltechnik in vielen Bereichen vorteilhaft die analoge Technik abgelöst. Um dies zu untermauern, muss man sich nicht auf die Errungenschaften in der Computertechnik beschränken. Herausragende Beispiele sind auch der digitale Mobilfunk, die digitale Fotografie und der digitale Rundfunk. Wie sehr gerade beim Letzteren die analoge Technik verwurzelt war und ist, zeigt sich daran, dass das Wort digital in den Bezeichnungen DAB, DVB-T explizit verwendet wird. So sind zwischenzeitlich die meisten analogen Basisstationen gefallen. Hartnäckig hält sich allerdings die analoge Technik in der Formung der Richtcharakteristiken von Antennen. Die Dissertation von Dr. Younis liefert in diesem Bereich grundlegende Beiträge zum sog. digital beam-forming speziell für die Radarsensorik. Hierfür wird in Mehrantennensystemen durch geeignete Raum-Zeit Signalverarbeitung eine äußerst flexible Strahlformung erreicht.

  • A Multi-Path Compensation Method for Ranging in Wearable Ultrasonic Sensor Networks for Human Gait Analysis
    sensors Article A Multi-Path Compensation Method for Ranging in Wearable Ultrasonic Sensor Networks for Human Gait Analysis Karalikkadan Ashhar 1,* , Mohammad Omar Khyam 2 and Cheong Boon Soh 1 1 School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Ave, Singapore 639798, Singapore; [email protected] 2 Department of Mechanical Engineering, Virginia Tech, Blacksburg, VA 24060, USA; [email protected] * Correspondence: [email protected] Received: 15 February 2019; Accepted: 14 March 2019; Published: 18 March 2019 Abstract: Gait analysis in unrestrained environments can be done with a single wearable ultrasonic sensor node on the lower limb and four fixed anchor nodes. The accuracy demanded by such systems is very high. Chirp signals can provide better ranging and localization performance in ultrasonic systems. However, we cannot neglect the multi-path effect in typical indoor environments for ultrasonic signals. The multi-path components closer to the line of sight component cannot be identified during correlation reception which leads to errors in the estimated range and which in turn affects the localization and tracking performance. We propose a novel method to reduce the multi-path effect in ultrasonic sensor networks in typical indoor environments. A gait analysis system with one mobile node attached to the lower limb was designed to test the performance of the proposed system during an indoor treadmill walking experiment. An optical motion capture system was used as a benchmark for the experiments. The proposed method gave better tracking accuracy compared to conventional coherent receivers. The static measurements gave 2.45 mm standard deviation compared to 10.45 mm using the classical approach.

Claus ‘ July, 1988 Blacksburg, Virginia PERFORMANCE EVALUATION OF CHIRP SPREAD SPECTRUM SYSTEM AND V LAND MOBILE SATELLITE SYSTEM BY COMPUTER SIMULATION bv Junghwan Kim Timothy Pratt, Chairman Electrical Engineering (ABSTRACT) 1— F The work presented in this dissertation examines the performance of two satellite radio j communication systems by computer simulation. Two simulations were separately performed for a spread spectrum chirp system as an analog communications system, and for the Land Mobile Satellite System (LMSS) channel as a digital communications system. For the simulation of analog communications, a spread spectrum system using chirp techniques called ’Coded Multiple Chirp Spread Spectrum’ was proposed as a simple, cost-effective alternative for conventional spread spectrum systems. Its application as a spread spectrum overlay service on analog FM-TV was examined through the mutual interference analysis and spectral analysis using soltware programming. For the simulation of digital communications, various digital modulation schemes as well as channel encoding, block interleaving/deinterleaving, and dltferential encoding techniques were used for a thorough performance evaluation of a Land Mobile Satellite System under fading conditions. For this purpose, an LMSS fading channel simulator capable of simulatlng diverse fading characteristics for a satellite channel was designed and tested to yield various performance measures such as symbol error rate and average bit error rate.

  • Effect of Photoacoustic Radar Chirp Parameters on Profilometric Information
    Effect of Photoacoustic Radar Chirp Parameters on Profilometric Information A thesis submitted to the Faculty of Engineering in partial fulfillment of the requirements for the degree of Master of Applied Science in Mechanical Engineering by Zuwen Sun Ottawa-Carleton Institute for Mechanical and Aerospace Engineering University of Ottawa Ottawa, Ontario, Canada, K1N 6N5 January 2018 © Zuwen Sun, Ottawa, Canada, 2018 Abstract Photoacoustic imaging for biomedical application has attracted much research in recent years. To date, most of the work has focused on pulsed photoacoustics. Recent developments have seen the implementation of a radar pulse compression methodology into continuous wave photoacoustic modality, however very little theory has been developed in support of this approach. In this thesis, the one-dimensional theory of radar photoacoustics for pulse compressed linear frequency modulated continuous sinusoidal laser photoacoustics is developed. The effect of the chirp parameters on the corresponding photoacoustic signal is investigated, and guidelines for choosing the chirp parameters for absorber profilometric detection are given based on the developed theory and simulations. Simulated results are also compared to available experimental results and show a good agreement. Key words: Photoacoustic, Pulse compression, Autocorrelation, photoacoustic radar. ii Acknowledgements My deep appreciation is presented to Dr. Natalie Baddour, who is my supervisor, for her patient help and professional advice during my study, as well as her financial support which made my life in Canada easier. I would also like to appreciate Dr. Liang Ming, who first gave me the opportunity to study at the University of Ottawa. At last, my grateful thanks to my parents, parents in law, and my uncle and aunt for their endless help and support.
