  • Wireless Military Communications - NNEC Enabler
    Wireless Military Communications - NNEC Enabler Miroslav Hopjan, Zuzana Vranova University of Defence, Department of Communication and Information Systems, Kounicova 65, 60200 Brno, Czech Republic [email protected]. [email protected] Abstract The paper discusses the NATO Network Enabled Capability concept, mainly from the communication point of view. The changes involve complete new requirements on the role of command and control to increase flexibility and effectiveness. Integration of Modeling and Simulation with Command, Control, and Information Systems increases the number of risks but it promises to leverage the projected capability and interoperability. Keywords: NNEC, simulation, tactical communication, CCIS. 1 Introduction This paper does not introduce new technological solution in wireless communications, the point of view is closer to the customer side of the house - how to use the emerging communication technologies in an optimal way supporting the concept of NATO Network Enabled Capability (NNEC) which emphasizes the role of information superiority in modem warfare. The aim is to evaluate number of aspects when implementing this technology in the Czech Army. What role is adequate for contemporary microwave devices, why the implementation is delayed, what risks must be outweighed by benefits of these solutions. Communications networking is the clearly visible part of the solution, and suitability of selected, mostly wireless communication approach, is discussed. Although it is not the core functionality for Command and Control Information Systems (CCIS) it is apparent that NNEC encompasses also Modeling and Simulation (M&S) capability. These two domains have developed different architectures, standards but further progress of one system is related to the other.

  • SDR and Cognitive Radio for Military Applications
    UNCLASSIFIED/UNLIMITED SDR and Cognitive Radio for Military Applications Tricia J. Willink Communications Research Centre 3701 Carling Ave., Box 11490, Station H Ottawa, ON, K2H 8S2 CANADA email:[email protected] ABSTRACT The development of software-defined radios (SDRs) should provide a small, light and cost-efficient platform capable of supporting multiple waveforms over a large frequency range. While there are challenges in achieving the vision of rapidly portable waveforms, the SDR is a critical technology for future military communications, and is an enabling platform for cognitive radio. Cognitive radio is proposed as a technology for exploiting the EM spectrum more effectively. While the main frequency bands of interest are fully licenced to authorised users, they are often unoccupied over large geographic areas or for significant time intervals. Cognitive radios are envisioned as aware, adaptable and intelligent devices, capable of learning and operating autonomously in a wide range of scenarios. The key feature of cognitive radios is the capability to identify unused frequency bands, to jump to them and select appropriate radio parameters. These radios must be able to operate without causing unacceptable interference to authorised users of the frequency band, therefore they must monitor for the presence of the primary user, and take into account the possible location of receivers of its signals. INTRODUCTION The adoption of the network-centric warfare (NCW), or net-enabled operations (NEOps), philosophy by western and allied nations requires a similarly revolutionary approach to communications technology. The basis of NEOps is the sharing of information among front-line forces, decision makers, sensors, weapons, etc.

  • An Undergraduate Course in Military Electronic Applications, Aka Electronic Warfare
    Paper ID #10790 An Undergraduate Course in Military Electronic Applications, aka Electronic Warfare Prof. Gene L. Harding, Purdue University GENE L. HARDING is an associate professor of Electrical and Computer Engineering Technology at Purdue University, where he has taught for eleven years. He has three years of industrial experience with Agilent Technologies and 28 years of combined active and reserve service in the United States Air Force. Page 24.176.1 Page c American Society for Engineering Education, 2014 An Undergraduate Course in Military RF Electronic Applications, aka Electronic Warfare Abstract An applications course can be a fun and interesting way to learn about an engineering discipline. The author created a course with a focus on what the military calls electronic warfare (EW): using the electromagnetic spectrum for advantage, preserving its use for friendly forces, and preventing the enemy from doing the same. During the course, his students explored several generally-applicable topics, including various types of radio frequency (RF) propagation, high- frequency printed circuit board (PCB) layout, and antenna analysis and design. They also studied several more militarily-focused topics, including different types of military systems used in EW, processing issues with EW signals, searching for RF transmissions, and locating hostile emitters. It is an upper-division course with an associated lab, and the author took an intentionally aggressive approach to the labs, pushing the limits of the available test equipment and facilities. As might be expected, this approach resulted in several “failures” during lab experiments, but also succeeded in pinpointing a number of issues to be addressed in future offerings of the course.

  • Re-Sourcing History the Cold War and the Birth of Satellite Communications
    Re-sourcing History The Cold War and the Birth of Satellite Communications Professor Kendrick Oliver Email: [email protected] Teaching and Research Specialisms: History of the United States from 1945 to 1980, including the Vietnam War, the Space Age, McCarthyism, evangelicalism, and the social and cultural history of the “big bang” theory of the universe’s origins. 1 Introduction This resource pack is designed to support A-level teaching and learning activities on the history of the Cold War, in particular by encouraging students to explore the significance of the Cold War in stimulating and shaping developments in the field of global communications. The legacies of the Cold War in terms of driving policy-makers to embrace the ideal of instantaneous worldwide communications are all around us today, below ground or on the ocean floor in the form of high-speed fibre optic cables, above us in the form of communication satellites. This pack introduces students to the geopolitical and security rationales behind American investments in civilian and defence satellite communications in the first thirty years of the Cold War. 2 Source 1: Chapter 2: The Significance of a Satellite Vehicle Attempting in 1946 to estimate the values to be derived from a development program aimed at the establishment of a satellite circling the earth above the atmosphere is as difficult as it would have been, some years before the Wright brothers flew at Kitty Hawk, to visualize the current uses of aviation in war and in peace. Some of the fields in which important results are to be expected are obvious; others, which may include some of the most important, will certainly be overlooked because of the novelty of the undertaking.
