摘　　要：实时逆合成孔径雷达(Inverse Synthetic Aperture Radar,ISAR)分辨率评估是判断舰船目标成像质量的关键,其评估结果直接决定了是否需要重复成像和应用于目标分类与识别的价值。介绍舰船目标ISAR成像原理,提出基于实时成像数据的分辨率计算和误差评估方法,进而给出基于误差评估结果的自适应ISAR成像方法。所提的计算方法和分析结果对于工程应用具有一定的参考价值。Real-time Inverse Synthetic Aperture Radar(ISAR)resolution evaluation is the key to judge the imaging quality of ship targets,and its evaluation results directly determine whether repeated imaging is necessary and the value of application in target classification and recognition.This paper introduces the principle of ISAR imaging for ship targets,proposes a resolution calculation and error evaluation method based on real-time imaging data,and then presents an adaptive ISAR imaging method based on error evaluation results.The proposed calculation method and analysis results have some reference value for engineering applications.
