Bistatic SAR system with GPS transmitter

Bistatic Synthetic Aperture Radar (BSAR) with GPS transmitter is in a focus of consideration. Bistatic topology, satellite transmitter of opportunity and stationary receiver, combined with inverse synthetic aperture radar (ISAR) technology with GPS P code modulated waveform for imaging of a moving are presented. Kinematical equations and mathematical model of the deterministic BSAR signal are created. It is proven that the signal formation and image reconstruction can be regarded as direct and inverse space transforms. Stages of image reconstruction, including phase correction, cross-correlation range compression and Fourier transform azimuth compression are defined. The effectiveness of models and algorithms are illustrated with results of numerical experiments.
