This paper puts forward a system concept for Bi-satellite Ka FMCW SAR. The system scheme and parameter design are given. And the receiving and transmitting antennas are also designed, which are proved correctly through the simulation and analysis of NESZ, RASR, and AASR. Meanwhile, the synchronization and internal calibration technology are also considered for the bi-satellite Ka FMCW SAR system preliminarily. Besides, based on the imaging algorithms researched before for the airborne Ka FMCW SAR, this paper proposes to use the modified w-k algorithm for multi-point targets imaging. The result and analysis present a further verify for the Ka-band Bi-satellite FMCW SAR system in this paper.
