Abstract :
In this paper, a new preprocessing approach is proposed for SAR ATR. The effect of DC (direct current) bias among images on the ATR performance is studied and a new preprocessing method is proposed. The alignment, amplitude compensation and DC bias removal can be done efficiently in the frequency domain. Experimental results are provided to demonstrate the performance of the proposed approach
