摘要

为了改善速度SAR系统的低速度分辨率，利用VSAR系统检测慢速运动目标，在VSAR系统的信号处理中采用现代频谱估计方法来代替传统的离散傅立叶变换方法。利用现代光谱估计可以获得比传统光谱估计更高的速度分辨率。它可以减少天线的数量和阵列的总长度，提高方位角分辨率。

A novel method of signal processing for VSAR system

To improve the low velocity resolution of a VSAR (velocity SAR) system and detect slowly moving targets with a VSAR system, modern spectral estimation in the signal processing of the VSAR system is used instead of the conventional DFT (discrete Fourier transform) method. Using modern spectral estimation one can achieve higher velocity resolution than with the conventional spectral estimation. It can decrease the number of antennas and the total length of the array, and improve the azimuth resolution.
