Elevation and Deformation Extraction from Tomosar

LANG FENG 2019-02-01 3 This page is intentionally left blank. 4 Abstract 3D SAR tomography (TomoSAR) and 4D SAR differential tomography (Diff- TomoSAR) exploit multi-baseline SAR data stacks to provide an essential innovation of SAR Interferometry for many applications, sensing complex scenes with multiple scatterers mapped into the same SAR pixel cell. However, these are still influenced by DEM uncertainty, temporal decorrelation, orbital, tropospheric and ionospheric phase distortion and height blurring. In this thesis, these techniques are explored. As part of this exploration, the systematic procedures for DEM generation, DEM quality assessment, DEM quality improvement and DEM applications are first studied. Besides, this thesis focuses on the whole cycle of systematic methods for 3D & 4D TomoSAR imaging for height and deformation retrieval, from the problem formation phase, through the development of methods to testing on real SAR data. After DEM generation introduction from spaceborne bistatic InSAR (TanDEM- X) and airborne photogrammetry (Bluesky), a new DEM co-registration method with line feature validation (river network line, ridgeline, valley line, crater boundary feature and so on) is developed and demonstrated to assist the study of a wide area DEM data quality. -

Spearrin, Chair Additive manufacturing (AM) has matured significantly over the past decade and become a highly attractive tool for reducing manufacturing complexity and removing traditional de- sign constraints. This is particularly desirable for rocket combustion devices which often feature hundreds of individual parts with precise tolerances. The degree to which AM can be used to improve combustion device performance, however, has been less rigorously ex- plored. In this work, hydraulic performance impacts associated with and enabled by AM are assessed for a liquid bi-propellant swirl coaxial injector. Specifically, a single-element liquid oxygen/kerosene injector based on a canonical design was manufactured from inconel using Direct Metal Laser Sintering at two different coaxial recess depths. Cold-flow testing for the as-manufactured baseline injector found a reduction in the designed discharge coefficients, which is primarily attributed to increased surface roughness inherent in the AM process. -

Final Environmental Assessment for Issuing an Experimental Permit to Spacex for Operation of the Dragonfly Vehicle at the Mcgregor Test Site, Mcgregor, Texas
THIS PAGE LEFT INTENTIONALLY BLANK Final Environmental Assessment for Issuing an Experimental Permit to SpaceX for Operation of the DragonFly Vehicle at the McGregor Test Site, McGregor, Texas AGENCY: Federal Aviation Administration (FAA), lead; National Aeronautics and Space Administration, cooperating agency. ABSTRACT: This Final Environmental Assessment (EA) addresses the potential environmental impacts of FAA’s Proposed Action of issuing an experimental permit to Space Exploration Technologies Corp. (SpaceX) for operation of the DragonFly reusable launch vehicle (RLV) at the McGregor test site, in McGregor, Texas. This Final EA evaluates the potential impacts of the operation of the DragonFly RLV as well as construction of a launch pad. Potential environmental impacts of the Proposed Action and the No Action Alternative analyzed in detail in this Final EA include impacts to air quality; noise and compatible land use; Department of Transportation Act: Section 4(f); historical, architectural, archaeological, and cultural resources; fish, wildlife, and plants; water quality (surface waters, groundwater, wetlands, and floodplains); natural resources and energy supply; hazardous materials, pollution prevention, and solid waste; light emissions and visual impacts; and socioeconomics, environmental justice, and children’s environmental health risks and safety risks. Potential cumulative impacts of the Proposed Action and the No Action Alternative are also addressed in this Final EA. PUBLIC REVIEW PROCESS: In accordance with the National Environmental Policy Act of 1969, as amended (NEPA; 42 United States Code 4321, et seq.), Council on Environmental Quality NEPA implementing regulations (40 Code of Federal Regulations Parts 1500 to 1508), and FAA Order 1050.1E, Environmental Impacts: Policies and Procedures, Change 1, the FAA published a Notice of Availability of the Draft EA in the Federal Register on May 21, 2014, which started a 30‐day public review and comment period. -

Spacex Launch Manifest
Small Launchers and Small Satellites: Does Size Matter? Does Price Matter? Space Enterprise Council/CSIS - October 26, 2007 “... several ominous trends now compel a reassessment of the current business model for meeting the nation’s needs for military space capabilities.” Adm. Arthur K. Cebrowski (Ret.) Space Exploration Technologies Corporation Spacex.com One of the more worrisome trends, from a U.S. perspective, has been the declining influence of American vehicles in the global commercial launch market. Once one of the dominant players in the marketplace, the market share of U.S. -manufactured vehicles has declined because of the introduction of new vehicles and new competitors, such as Russia, which can offer launches at lower prices and/or with greater performance than their American counterparts.
