摘要

本文提出了一种基于联合像素的三通道地面运动目标检测(GMTI)方法.首先分析联合像素处理后的两多视SAR图像干涉统计特性

建立幅相联合的概率统计模型

分析虚警和漏警

考虑到最小可检测速度内存在速度模糊

采用能量重心法解模糊

最后将干涉幅度和解模糊后的干涉相位联合检测动目标.实测数据处理结果验证了该方法的有效性.

Abstract

A new method based on joint pixel interferograms is proposed for three-channel ground moving target indication (GMTI).Firstly

a joint probability statistical model is established using the statistical properties analysis of multilook SAR interferograms after joint pixel processing.Then the false and leak alarms are analyzed.Meanwhile

considering the velocity ambiguity in the range of minimum detectable velocity (MDV)

an energy center method is presented to resolve ambiguity.Lastly

the interferometric magnitude and unambiguous phase are jointed to detect moving targets.The validity of new detection method is demonstrated by the results from real data.
