| 摘 要： | 分析了传统地杂波计算中将地表只进行“等距等多普勒”划分的缺点,提出了“等距等多普勒等波束”划分的思想;针对划分后网格单元形状异常复杂的问题,提出了一种依据上述划分思想的方格划分方法及其计算步骤。其最大特点是各方格单元面积相同,直接避免了网格单元面积的计算问题。仿真结果证明了方法的有效性。

| Abstract: | In traditional methods for calculating ground clutters, the ground is always partitioned by "range-Doppler" curves. But this partition is not precise enough. To overcome its drawbacks, a new partition idea called "Doppler-range-beam" is put forward. In view of the complexity of the ground cells' shapes, a new partition method called "EAP" is presented. Its prominent merit is that all the grid cells have equal areas, thus avoiding area calculation of ground cells directly. Simulations support the conclusion. |
