为了解决导引头杂波功率精确计算的问题,提出了一种新的判断杂波功率积分区域的方法.该方法借助于等多普勒线和等距离圆的不同空间位置关系,遍历划分完备各种球坐标下距离门和速度门决定的积分区域形状,根据每一种情况分析其积分区域.该方法在由导引头速度门、距离门所确定的区域内实现精确的积分区域定位,并对每一种杂波积分区域进行相应的说明.仿真结果验证了该方法的实用性和可行性.

Rigorous Calculation Method of Clutter Integration Region of Radar Seeker

In order to precisely calculate the clutter power of the radar seeker, this paper presents a new method of judging the ground clutter integration region of radar seeker. According to the geometric relationship between the iso-range lines and iso-Doppler, the shapes of integration regions, which are decided by distance and velocity gate under various sphere coordinates, can be partitioned. This method can precisely locate the ground clutter integration region under specified range gate and velocity gate of the radar seeker. The detailed instruction and analysis are given for each of these regions. Finally, the simulation proves the feasibility of the presented method.
