摘　　要：本文介绍了机载雷达目标识别技术的现状,以及现有机载雷达所采取的目标识别技术,并用试验验证了机载雷达对岛屿与小型船只的分类能力。说明应用步进频体制可实现对目标与背景的高分辨距离成像,通过该体制可提取出目标的距离维尺度特征。该技术可用于区分海域中的岛礁、小型舰艇、大型舰船等尺度差异较大的目标与背景。This paper introduces the current situation of target recognition technology of airborne radar and the target recognition technology adopted by the existing airborne radar.The classification ability of airborne radar for islands and small ships is verified by experiments.It is shown that high resolution range imaging of target and background can be achieved by using step frequency system,through which the range dimension scale features of target can be extracted.The technology can be used to distinguish the targets and backgrounds with large scale differences such as reefs,small warships and large warships in the sea area.
