为解决地波雷达一阶海杂波内船只目标检测的难题，提出了一种利用风浪流等现场海态观测信息检测海杂波内目标的方法。该方法通过对比实测雷达回波谱和基于现场海态观测信息重构的无目标回波谱，发现实测雷达回波谱中一阶谱频率范围和左右峰值比等特征的异常变化，实现船只目标的检测。将该方法应用于实测地波雷达数据，并利用同步的船舶自动识别系统信息（A IS ）对检测结果进行了验证，结果表明本文方法是一种有效的一阶海杂波内目标的检测方法。

To solve the ship detection problem in the first order sea clutter of High Frequency Surface Wave Radar (HFSWR) ,the spectrum reconstruction and the analysis of the influence of the ship targets to the first order spectrum were analyzed .Further ,a target detection method using sea state measuring data was proposed .The abnormal detection of frequency range and the first‐order peak ratio were performed to fa‐cilitate the target detection using HFSWR field data and spectrum reconstructed by sea current ,wind di‐rection and sea wave information .The detection results were verified by the synchronous ship Automatic Identification System (AIS ) information and the detection method presented is effective in detecting the ship target in first order sea clutter .
