Abstract
Geometric or angular diversity can be exploited to significantly enhance ultrahigh frequency (UHF) synthetic aperture radar (SAR) imaging performance, to capture target glints, to exploit highly directional specular returns, to achieve enhanced resolutions in both planar dimensions without increasing the radio frequency (RF) bandwidth, and to form three-dimensional (3-D) images using a large aperture and a steep grazing angle. These improvements are especially important for urban target detection and surveillance in cluttered environments. Several key technical challenges, however, must be overcome to reap the benefits afforded by the geometric diversity. The first objective of this program is to develop effective and efficient high resolution UHF SAR imaging algorithms by exploiting the geometric diversity offered by the wide angle concept. The second objective of this program is to evaluate and test the performance of our algorithms using simulated and measured data available to us. The goal of these investigations is to determine the merits and limitations of the algorithms and to establish tradeoffs between coverage, resolution and target detection performance. We will identify promising ideas and algorithms for further investigations during Phase II. BENEFIT: The technologies we develop can be applied to many civilian radar applications, including better air traffic control and monitoring, improved domestic counter-terrorism, enhanced boarder security, and more reliable drug trafficking monitoring.
