Research on Bistatic SAR Imaging

For reasons of stealth and other operational advantages, more attention has recently been focused on bistatic SAR Bistatic SAR uses separated transmitter and receiver flying on different platforms, and has the ability of the exploitation of additional information contained in the bistatic reflectivity of targets. Besides of technical problems - like the synchronization of the oscillators - the processing of bistatic raw data imaging is not well studied theoretically all the same, which is a major area in bistatic SAR. This paper firstly describes the special case of equal velocity vectors and parallel flight paths of transmitter and receiver, and then makes detailed and mathematical study on the approximate bistatic-to-monostatic application (BTMA). Based on the BTMA, the bistatic imaging can be processed with a Standard SAR Processor.
