频积累时要求信号间有严格的相位关系,也就是说
信号是相参的,所以也称为相参积累。此外,积累
过程可以在包络检波后完成,称为检波后积累或者
视频积累。由于信号在包络检波后失去了相位信息
而只保留了幅度信息,所以检波后积累处理就不需
要信号间有严格的相位关系,因此这种积累又称为
非相参积累。实现非相参积累的方法有很多,例如
抽头延迟线积累(FIR 积累)器和反馈积累器。

论文分析了合成孔径雷达图像迭代滤波处理的效果及其问题,结合统计滤波方法和小波分析方法,提出了一种基于细节补偿的MAP迭代滤波算法。实验结果表明,新的迭代滤波算法较好地解决了去噪和细节保留之间的矛盾,而且算法稳定,收敛很快。(This paper analyzes the iterative synthetic aperture radar image filtering effect and its problems, combined with statistical filtering methods and wavelet analysis method, details of compensation, a MAP based iterative filtering algorithm. Experimental results show that the new iterative filtering algorithm can solve the denoising and detail preservation conflicts between, and the algorithm is stable and fast convergence.)
