摘　　要：针对分布式干扰机掩护目标突防雷达网背景下的干扰资源分配问题,提出了一种引入随机密钥的改进离散模拟退火遗传算法(improved discrete simulated annealing genetic algorithm,IDSA-GA)对资源分配过程进行优化。基于雷达网融合检测概率构建干扰效果评估函数,利用IDSA-GA对函数寻优求解。IDSA-GA在模拟退火遗传算法(simulated annealing genetic algorithm,SA-GA)的基础上引入随机密钥,完成算法的离散化;并在迭代的过程中增加记忆功能,克服了过早收敛的现象。仿真结果表明,与GA相比,提出的IDSA-GA收敛迅速,寻优能力强,能有效解决干扰资源优化分配问题。An improved discrete simulated annealing genetic algorithm(IDSA-GA)with random keys is proposed to optimize the resource allocation process in the context of distributed jammers covering target penetration radar networks.An interference effect evaluation function based on the fusion detection probability of radar networks is constructed,and IDSA-GA is used to optimize and solve the function.IDSA-GA introduces random keys on the basis of simulated annealing genetic algorithm(SA-GA)to discretize the algorithm.And during the iteration process,memory function is added to overcome the phenomenon of premature convergence.The simulation results show that compared with GA,the proposed IDSA-GA converges quickly and has strong optimization ability,which can effectively solve the problem of optimizing interference resource allocation.
