为了解决海杂波引起的船用连续波雷达虚警概率增大,以及海杂波抑制算法工程应用难度大的问题,提出了一种工程实用的海杂波抑制方法.首先,通过双参数删除型CFAR检测算法和统计检测算法进行二次检测;然后,依据邻近帧之间目标回波相关性较强和片状海杂波相关性较弱的特点进行帧间处理.仿真和海上实验均表明,应用该方法的船用连续波雷达可以降低不同强度的海杂波背景下的虚警概率.

@@@@In order to solve increasing of probability of false alarm caused by the marine continuous wave( CW) radar sea clutter, as well as difficulty of sea clutter suppression algorithm engineering applications, a practical engineering sea clutter suppression method is proposed . First, secondary detection is performed by biparametric delete constant false alarm rate(CFAR) detection algorithm and statistical detection algorithm . Then,according to the feature that the target echo correlation between adjacent frames is strong and flaky sea clutter correlation is weak,the interframe processing is carried out . Simulation and sea experiments show that through application of the method marine CW radar can reduce the probability of false alarm under different intensities of sea clutter .
