摘　　要：在考虑近海岸复合杂波的情况下,从地海复合杂波生成原理入手,以机载PD雷达杂波功率谱闭合算法为基础,通过简化海岸线几何形状,给出了在此环境下机载PD雷达杂波功率谱计算的一般算法。分别对陆地环境杂波功率谱和近海岸环境复合杂波功率谱进行了仿真。仿真结果表明,较之陆地环境,近海岸环境下机载PD杂波功率谱分布具有更加复杂的特性,并证明了此一般算法的有效性。Based on the generation principle of the compound sea and ground clutters and the closed algorithm of the clutter power spectrum of the airborne PD radars in the coastal environment, a general algorithm of the clutter power spectrum is given through simplifying forms. The simulations of the clutter power spectrum in the land and coastal tively done, and the results show that the distribution of the clutter power PD radars in the coastal environment is more complex than that in the land gorithm proves to be effective. the coastline geometric environment are respecspectrum of the airborne environment and the al-
