为全面、有效衡量用于应急测控的直扩/跳扩(DS/FH)系统的综合抗干扰性能,采用最低性能指标约束法,对系统抗干扰性能进行综合分析.以音调干扰、脉冲干扰以及高动态环境为例,探讨了不同干扰条件对系统最低性能指标的影响.为解决最低性能指标约束下系统抗干扰性能测试步骤繁多、效率低、代价高的不足,采用蚁群算法,将指标测试次序建模为最佳路径选择问题.通过实例仿真验证了测试模型的正确性与有效性.该方法对DS/FH测试方案的选择具有指导意义.
In order to comprehensively and effectively measure the comprehensive anti-jamming performance of DS / FH system used for emergency measurement and control, the performance of the system is analyzed by using the lowest performance index constraint method. High dynamic environment as an example, the influence of different interference conditions on the lowest performance index of the system is discussed.In order to solve the problems of many steps, low efficiency and high cost of anti-interference performance under the constraints of the lowest performance index, an ant colony algorithm Order as the optimal path selection problem.The correctness and validity of the test model are verified through an example simulation.This method is instructive for the choice of DS / FH test scheme.
