摘　　要：阐述了干涉式逆合成孔径雷达(ISAR)三维成像的基本原理,与传统的ISAR二维成像方法的性能进行了比较。结合实际的宽带雷达平台,介绍了试验验证的基本方法,并通过静态双散射点和过航飞机等目标的实际跟踪试验,获取了目标回波信号的和、方位差和俯仰差三通道宽带数据,给出了干涉ISAR三维成像的算法流程。采用干涉ISAR三维成像的算法对实际测量数据进行了处理,得到了各类目标的成像结果,对成像效果进行了分析和评估,提出了工程应用的建议。The basic principle of interferometric inverse synthetic aperture radar（ISAR） 3-D imaging is introduced, the performance is compared with traditional ISAR imaging. Based on real wideband radar, the testing method is introduced, and the wideband data of three channels which are range sum, azimuth difference, elevation difference is achieved by the test of tracking targets including static double scattering points and passing planes, etc. The interferometric ISAR 3-D imaging algorithm is introduced. The data is processed adopting the algorithm, the imaging results are given, analyzed and evaluated. The future engineering suggestion is given.
