【摘要】 相干斑是SAR相干成像中固有的乘性干扰,而多视是一种与成像算法相结合、工程上实用的抑制相干斑的方法。本文对文献[1]提出的多视方法,进行了改进,使算法更为简便,同时相关不完全的点不用弃置,增加了场景的范围,便于工程实现。最后用实测数据验证了本文介绍的对多视的改进的有效性。更多还原

【Abstract】 Speckle is an implicit multiplicative noise with SAR imaging,and multi-look.which is combined with imaging algorithms and practical in the engineering,is a method to restrain speckle.This paper modified the multi- look method proposed in document[3],make the a lg orithm easier and not need throw away those signal dots which is not matched completely,so increase the scope of scene and is easy to implement in engineering.In the end,the modified multi- look method introduced in this paper is verified with SAR real data.更多还原
