Non-linear chirp scaling algorithm for one-stationary bistatic SAR

This paper points out the non-linear property of the differential RCM along range direction in one-stationary bistatic SAR, and compares it with the monostotic case. Then it deduces out a non-linear chirp scaling factor to identify the RCM of all targets in the swath. The implementary processes of a non-linear chirp scaling algorithm for one-stationary bistatic SAR are then described detailedly. Finally, the simulating results present here validate the correctness of the algorithm.
