| 摘 要： | 针对机载合成孔径雷达（ＳＡＲ），分析了运动目标的检测和成像处理的方法，通过对Ｗｉｇｎｅｒ－Ｖｉｌｌｅ分布（ＷＶＤ）同Ｗａｖｅｌｅｔ变换（ＭＴ）的分析和比较，将ＡＤＰＣＡ（ＡｄａｐｔｉｖｅＤｉｓｐｌａｐｈａｓｅＣｅｎｔｅｒＡｎｔｅｎｎａ）同ｗＴ相结合，从而达到对运动目标进行检测和成像的目的。对ＡＤＰＣＡ的对消比的计算机模拟，表明ＡＤＰＣＡ具有良好的杂波抑制能力。最后给出了可行的运动目标检测和成像的框图。

| Abstract: | This paper analyses the algorithm of moving targets detection and imaging of airborne SAR(Synthetic Aperture RAda).By comparing WT(Wavelet Transform)and WVD(Wigner-VilleDistribution),this paper combines ADPCA(Adaptive Display phase CenterAntenna )technique with wT(Wavelet Transform) in moving targets detection and imaging.The simulation result of ADPCA shows thatADPCA has great ability in clutter suppression. At the end of this poper,the usable and reliabile scheme formoving targets detection and imaging is given. |
