摘　　要：在子带脉冲压缩方法的基础上,对多通道幅相误差对合成图像质量指标的影响进行了详细分析,发现子带脉冲压缩方法对通道间的不一致相位误差不敏感,幅度误差是造成图像的峰值旁瓣比和积分旁瓣比指标恶化的关键因素,因此需要对通道间的不一致幅度误差进行补偿。In this paper, synthesis method with subband pulse compression is studied and the emphasis of the article is on the analysis of the influences of channels＇ amplitude and phase errors on image performance indexes. The statistical simulation result shows that the phase errors between channels have low effects on this method, and the amplitude errors are the main factors of the losses of the ratio of peak value side lobe and the ratio of integral side lobe of images. So the eompensation of the channels＇ amplitude errors is necessary.
