Paper Abstract

The SIR-C/X-SAR experiment, a joint effort of NASA, DARA/DLR, and ASI, is a multi- frequency, multi-polarization synthetic aperture radar (SAR) system for spaceborne scientific Earth imaging scheduled for initial launch in April 1994. Its predecessors include the L-Band, single-polarization Seasat, SIR-A, and SIR-B missions of the late 70's and early 80's. Since SIR-C/X-SAR is intended to be the predecessor to the multi-frequency, multi-polarization EOS SAR satellite, it serves to demonstrate and validate various advanced SAR architectures and data products. This paper documents the architecture and performance of the SIR-C L-Band and C-Band active SAR arrays, with emphasis on RF test results and expected performance. Performance at the array level is extrapolated from measurements at the T/R module and antenna subarray levels.
