基于雷达仿真训练器的地面杂波算法

在雷达仿真训练器中，地面杂波的计算是比较复杂的。首先它与太多的环境因素有关，建模困难；其次近似计算比较多，误差大。为了解决地面杂波的仿真问题，通过对雷达方程的研究，并针对实际的地形数据，采用微积分的思想，将大面积的无规律的雷达截面积化为小地面的有规律的截面积进行叠加，从而提出了一种建模思路。实验结果也基本符合实际。

The Arithmetic of Landform's Echo Wave Based on the Radar Simulation

The calculation of landform's echo wave is very complicated in the radar simulation. In the first, it is related to many environmental factors and the modeling is difficulty. The second, there is much approximate calculation and the error will be accumulated. In order to solve the simulation of the landform's echo wave, I study the radar equation and the actual landform's data. I adopt the calculus idea and convert the big ruleless radar's section to the accumulation of small rule radar's section , and then bring forward a new modeling idea. At last, the result accords with the fact.
