摘要
对某型舰载搜索雷达采集的海杂波数据进行了简要的海杂波频谱分析,并对有船只和无船只的海域回波信号频谱作了对比,采用动目标检测(MTD)和频域杂波图恒虚警处理来抗海杂波,并针对频域杂波图恒虚警处理中虚警率增加的问题,提出了频域杂波图恒虚警与单元平均恒虚警级联的改进方案。
The paper carries on the brief sea-clutter frequency spectrum analysis to sea-clutter data collected by a certain shipborne search radar,and makes a comparison between the frequency spectrum of echo signals in the sea area with ships and the sea area without ships,adopts moving target detection （MTD） and constant false alarm processing by frequency domain clutter chart to confront with the sea clutter,and puts forward the improved scheme combined the constant false alarm processing by frequency domain clutter chart with unit average constant false alarm according to the problem that the false alarm rate increases in the constant false alarm processing by frequency domain clutter chart.
