The radio frequency spectrum has become very crowded with the increased use of commercial and personal communications devices. The worldwide spectrum committees require extreme measures to insure frequency avoidance by radar systems, to insure communications are maintained for emergency systems and flight safety. Radars operating in the frequency bands below 2 GHz have limited spectrum allocation,...
This paper derives a closed form expression for the distribution of the multi-look phase variable from elementary considerations for zero mean Complex Gaussian data, and further uses the results to justify the thresholding often used in along track interferometry (ATI). Further the target in clutter (TIC) problem is addressed as a hypothesis testing problem and the effect of the environment and target...
This paper presents a new adaptive radar signal processing technique for target detection and geolocation using radar data from platforms capable of performing simultaneous Synthetic Aperture Radar (SAR) and Along-Track Interferometry (ATI). Space-Time Adaptive Processing (STAP) and ATI processing methodologies are combined in parallel to simultaneously image, detect and identify the geolocation of...
Recent advances in wideband digital waveform generation, analog-to-digital converters (ADC) and high speed parallel processing provide the technology to develop ultra wideband systems for simultaneous synthetic aperture radar (SAR) and ground moving target indication (GMTI) modes. A system equipped with this capability will provide uninterrupted coverage on targets entering and exiting the main-beam...
