Sea clutter simulation and acceleration for PD radar

摘要:

为了提高杂波仿真的精度和速度,提出了一种对现有杂波模型的改进方法,即改用Petts的海杂波后向散射系数模型提高仿真精度,通过预先存储网格单元面积积分、只实时计算主杂波和查表实现旁瓣杂波提高仿真速度。仿真结果表明:该算法有效地提高了杂波仿真的精度和速度。

Abstract:

In order to simulate the clutter quickly and accurately, a method to modify the existing clutter model is introduced in this paper. It improves the simulating speed and precision by means of Petts’s sea clutter model and prestoring the area unit. The main clutter is only calculated in real time and table looks up the side clutter. The results show that it improves the speed and precision of the clutter simulation greatly.
