Study of range-Doppler imaging using real data in microwave anechoic chamber

In this paper, several rotating target imaging methods are investigated. They are FFT range-Doppler processing, extended coherent processing, polar format processing, the CBP algorithm and a novel superresolution imaging approach using the linear prediction technique. Quality images of a rotating target in a microwave anechoic chamber by the above five imaging methods have been obtained. The resolution limitation, the SNR performance and the computational complexity of these image reconstruction approaches are evaluated and compared
