摘　　要：为提高区域雷达网探测能力和抗干扰能力,提出了一种基于微分进化算法的雷达网优化布站方法。建立区域雷达网优化布站数学模型,分析了雷达网在干扰前后威力区的变化,提出了新的雷达网威力区计算方法,给出了微分进化算法在该优化问题中的求解过程。最后,针对雷达网受干扰后威力区收缩,提出了2种解决方案。仿真结果证明该优化方法是有效的。In order to improve the detective and anti-jamming performance of radar net, an optimal disposition method based on differential evolution algorithm （DE） was presented. A mathematical model for radar optimal disposition was established. By analyzing the detection scope＇s change with/without jamming of radar net, a new method to calculate the detection scope was proposed and the solving process of DE for this optimization problem was discussed. At last, for the detection scope gets shrinking when jammed, two different projects to solve this problem were proposed. Simulation results show that this project is effective and feasible.
