复杂地形环境下雷达效能仿真并行算法设计

摘要

研究雷达效能优化问题,针对确定雷达的有效探测覆盖范围,确定目标的可测性,在复杂地形环境下雷达覆盖范围的计算是一个计算量较大的问题,必须考虑可能覆盖区域中每一点所处的地形地貌特征,以确定目标在位置的可探测性.为了提高仿真计算效率,分析了并行方式进行雷达覆盖范围基本原理,提出了一种雷达覆盖范围仿真方法,并利用MPI平台进行了仿真.仿真结果表明,方法可有效提高复杂地形环境下雷达效能仿真计算的效率,可以实现大场景和复杂地形条件下的雷达效能仿真,并提供了高效实现方法与途径.%One of the key problems in radar effectiveness simulation is to determine the effective coverage area. However, it is a computation-intensive problem under complex terrain environment, because terrain characters of each district must be considered in detail. To improve the simulation efficiency, this paper studied the basic principle of parallel simulation of radar coverage simulation, and put forward a method, which modeled the above problem as an embarrassingly parallel problem by dividing the possible radar coverage area. MPI is used for implementation and experimentation. The result shows that, this parallel algorithm can significantly improve the computation speed of the radar coverage computation under complex terrain environment, providing an efficient way for large-scale radar coverage simulation.
