摘要
针对机载PD雷达的工作特点,结合Morchin的后向散射系数模型,按照等距离-等多普勒网格法划分,分析了地杂波功率谱计算方法的推导过程和计算细节,提出了通过预先计算存储地杂波的散射单元面积、后向散射系数来提高功率谱运算速度的计算方案。
According to the characteristics of airborne PD radar, combined with the Morchin backscattering coefficient model, and according to the distance-Doppler method of grid division, the paper described in detail the clutter power spectrum calculation details of derivation and calculation method, and at last put forward by pre-computing storage ground clutter scattering unit area, wave backscatter to improve the pow- er spectrum calculation speed coefficient.
