| Abstract: | Based on basal principle of RCS and Fourier transform ,the paper introduces time domain RCS measurements of ship using fast fourier transform, and analyses the advantage of time domain measurements and the application of FFT in time domain measurements. As a result, using the technique of fourier transform in time domain RCS measurements of the target can greatly improve measurements precision . |
