摘要 舰载雷达和海岸警戒雷达的目标检测和跟踪性能与海杂波密切相关。对X波段雷达实测海杂波进行了功率谱密度和相关分析,得到了一些有益的结果。与VV极化相比,HH极化的海尖峰特性更明显;与HH极化相比,VV极化海杂波的功率谱密度具有更窄的带宽,且衰减得更快。而HH和VV极化海杂波具有相似的相关性,但HH极化的相关系数要比VV极化的要小。得到的结果对雷达目标检测与识别具有一定的借鉴意义。 The target detection and tracking performance of shipborne radar and coast warning radar, is closely related to sea clutter. The power spectrum density and correlation analysis is done on the experimental data of sea clutter with X-band radar, and some helpful results are thus obtained. Compared with VV polarization, the spike of sea clutter in HH polarization is more obvious, and compared with HH polarization, the band width of power spectrum density of VV polarization is smaller and decays more rapidly. However, of both HH and VV polarization of sea clutter have similar correlation properties, but the coefficient of HH polarization is smaller than that of VV polarization. The experimental results given in this paper are of certain reference value to the target detection and recognition of radar.
