Bistatic Generalized ISAR concept with GPS waveform

Bistatic Generalized Inverse Synthetic Aperture Radar (BGISAR) concept is considered. Bistatic topology, satellite transmitter of opportunity and stationary receiver, combined with inverse synthetic aperture radar (ISAR) technology with GPS C/A code modulated waveform for imaging of a moving target and forward scattering principle are presented. Kinematical equations are derived. A mathematical model of the deterministic BGISAR signal is 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 experiment.
