摘　　要：为了解决雷达信号环境模拟器中脉冲重叠导致的脉冲丢失问题,提出了一种遗传算法优化的多通道雷达信号合成方法。首先分析了脉冲丢失率的概率分布,并设计了多通道雷达信号合成方法流程,并以优先级排序方法取舍脉冲实现信号合成策略,同时以遗传算法对时域上冲突的多路信号进行一定时延时间优化,实现了典型的2路射频通道雷达信号合成硬件结构。仿真结果表明,该方法的软硬件方案可以有效降低脉冲丢失率,提升雷达信号环境模拟器的效率和逼真度。In order to solve the problem of pulse loss caused by pulse overlap in radar signal environment simulator,a multi-channel radar signal synthesis method optimized by genetic algorithm is proposed. Firstly,the probability distribution of pulse loss rate is analyzed,and the process of multi-channel radar signal synthesis method is designed. The signal synthesis strategy is realized by choosing pulses by prioritization method. At the same time,the genetic algorithm is used to optimize the time delay of conflicting multi-channel signals in time domain,and the typical hardware structure of two-channel RF radar signal synthesis is realized. The simulation results show that the software and hardware scheme of this method can effectively reduce the pulse loss rate and improve the efficiency and fidelity of radar signal environment simulator.
