由于应用干涉图对地面慢动目标进行检测时表现出巨大的潜力,因此备受国内外SAR-GMTI研究者们的青睐.在分析和对比了各种基于干涉图的双通道SAR(D-SAR)图像域地面慢动目标检测算法的基础上,首先,对现有算法进行了归纳分类;然后,分析比较了每类算法的基本原理,并阐明了他们各自的优缺点;进而结合实验验证,分别从检测率和虚警率、稳健性、可检测速度范围以及抗干扰性等方面做了进一步的对比分析,并全面总结了现有算法的检测性能;最后,结合现有算法存在的不足,指出了下一步的研究方向.%Dual-SAR interferometry shows great potential for detecting the slow ground moving targets. Firstly, according to a performance analysis and comparison of the slow ground moving target detecting algorithms based on interferometry, all the algorithms are divided to three categories. Then, on the basis of analyzing the basic detection theory of each interferometry algorithm, this paper illuminates their advantages and disadvantages. By combining with the simulated results, further analysis and comparison are conducted in terms of detection probability and false alarm probability, the stabilization, the range of detection velocity, anti-jamming. Finally, by summarizing the disadvantages of each interferometry algorithm, this paper indicates the practical use of interferometry for detecting slow ground moving targets.
