摘　　要：在地杂波功率谱闭合计算算法的基础上提出了地杂波功率谱实时算法,即对功率谱闭合计算法参数及结果进行了分类比较,事先存储计算量最大的所有网格单元面积及其方向坐标,实时构造最大速度下功率谱,然后利用数据抽取的方法,得到当前速度下的功率谱,解决了实时性与高精度的矛盾,并给出了仿真结果。仿真结果表明该算法的有效性。High speed and precision can be achieved by making use of the clutter power spectrum density （PSD） closedform algorithm for the airborne PD radar when the area units are pre-stored. The PSD corresponding to maximum velocity is reconstructed in real time, and then the clutter PSD of present velocity is obtained using the decimation technology. Based on this theory, this paper introduces a real-time clutter simulation algorithm, and computer simulation is made. The results have affirmed the validity of this algorithm.
