摘要：
Comparing with traditional way of continue-wave RCS measurement system, high-resolution information is gained in stepped-frequency system. Using inverse fast Fourier transform, the frequency-domain data of the whole chamber obtained by testing is interpreted into high-resolution time-domain response, and the unwanted signals can be removed by adding a gating function. The measurement of finite frequency spectrum makes a cut of data; the use of windows reduces the effect of side lobe. Some experiments show that the accuracy will be improved after the signal processing techniques are used.
