Experimental results for shadow inverse synthetic aperture radar

Bistatic shadow inverse synthetic aperture (SISAR) offer a number of promising features such as: simple hardware; enhanced target radar cross-section (RCS); a long coherent interval of the diffracted signal; robustness to stealth technology; In spite of a number of theoretical research efforts in the application of SISAR for target imaging, there are few experimental results available that are able to confirm the theory and specify problems of SISAR´s practical design. This paper is dedicated to the experimental study of the feasibility of SISAR micro-sensors for the imaging of ground vehicles. A motion compensation method based on waveform entropy is presented in the paper. Finally experimental results, conclusions and recommendations are presented.
