Ultra wideband Bistatic Forward Scattering Inverse Synthetic Aperture Radar imaging

In this work Bistatic Inverse Forward Scattering Inverse Synthetic Aperture Radar (BFISAR) concept is addressed. Geometric description of BFISAR topology with stationary transmitter and receiver, and moving target is given. Kinematic vector equations are derived. Mathematical model of BFISAR signal with linear frequency modulation (LFM) is described. It is proved that BFISAR signal formation and image reconstruction can be interpreted as direct and inverse projective operation respectively. Through Taylor expansion of the projective operator basic image reconstruction procedures, including phase correction, Fourier transform range compression and Fourier transform azimuth compression are defined. Numerical experiment to verify mathematical models derived is carried out.
