Abstract:

The main objective of this effort was to develop a computer based analytical capability for simulating the RF performance of large space-based radar SBR systems. The model is capable of simulating corporate and space fed aperture. The model also can simulate multibeam feeds, clusterpoint feeds, corporate feed and various aperture distributions. The simulation is capable of accepting Draper Labs structural data and antenna current data from Atlantic Research Corporations ARC First Approximation Methods FAM and Higher Approximation Methods HAM models. In addition there is a routine to input various apertures surface distortions which causes the elements in the arrays to be displaced from the ideal location on a planar lattice. There were analyses looking at calibrationcompensation techniques for large aperture space radars. Passive, space fed lens SBR designs were investigated. The survivability of an SBR system was analyzed. The design of ground based SBR validation experiments for large aperture SBR concepts were investigated. SBR designs were investigated for ground target detection.
