摘要
交叉项问题是合成孔径雷达信号处理的主要难题,为了解决常规的合成孔径雷达信号处理中的交叉项问题,从Wigner-Ville引出Wigner-Hough变换的原理,及Wigner-Hough变换处理这一问题的方法。通过Matlab软件仿真实验,比较常规方法与Wigner-Hough变换处理后的合成孔径回波信号效果,经过Wigner-Hough变换处理后的回波信号解决了交叉项问题,凸显Wigner-Hough变换在处理合成孔径信号中的优势。
Cross-term is the critical problem of SAR signal processing. To solve it in the signal processing,the transform principles of Wigner-Hough were drawn forth from the Wigner-Ville,and then the method to deal with the problem in the Wigner-Hough transform was determined. The effects of the SAR echo signal of common methods and the Wigner-Hough transform method were compared by Matlab simulation experiment. The superiority of Wigner-Hough transform is obvious for processing the syn-thetic aperture echo signals.
