摘要
利用对引信波束照射区域进行单元划分并矢量叠加回波信号的方法进行杂波仿真可以获得较高的逼真度,但是计算量也成倍的增加。在对引信接收杂波仿真过程深入研究的基础上,提出并行计算方法解决杂波仿真效率低的问题。该方法基于脉冲重复周期的粗粒度划分并解决了负载平衡问题。仿真试验充分验证了该方法的有效性和可行性。
The fuze received clutter simulation method of adding vector echoes from small cells in the area of antenna illuminating can obtain high fidelity, but the calculation multiplies. A parallel computing method was proposed based on deep research on clutter simulation to solve the problem of low simulation speed In this method, a coarse grained division according to the Pulse Repetition Time was used and the load balance was resolved. The simulation result adequately testifies the validity and feasibility of the method.
