Abstract :
We present a modified SPECAN algorithm for missile-borne SAR in flat flight mode. Using the proposed technique, long azimuth sequence can be processed at memory constraint which is helpful for real time imaging. In addition, spectrum overlap can be avoided by changing kernel of chirp-z transform and data selection. Experiments on simulated data are carried out to validate the theory.
