摘　　要：机载对海逆合成孔径雷达(inverse synthetic aperture radar, ISAR)能够对海面大中型舰船进行二维成像,图像信息为识别提供了更有利的依据.根据ISAR系统的工作原理,首先分析了对海多目标ISAR面临的关键问题;然后提出了空间、时间两维分割的处理方案,以解决不同海况下海面多目标成像分辨率的问题;最后给出了典型的试验验证结果.本文的研究结果对海面多目标ISAR系统设计具有一定的指导意义.Airborne maritime inverse synthetic aperture radar(ISAR)can be used for two-dimensional imaging of large and medium-sized ships on the sea surface,and the image information provides a more favorable basis for target recognition.According to the working principle of ISAR system,this paper first analyzes the key problems that ISAR faces when processing the sea-surface multi-objectives,and then puts forward a time-space two-dimensional partition processing algorithm to solve the problems of imaging resolution of multi-objectives under different sea conditions.Finally,the paper presents the typical experimental verification results.The test results of this paper have certain guiding significance for the design of sea surface multi-objective ISAR system.
