摘要
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.
Based on the Minimum Performance Constraint （MPC）, a synthetic analysis method was presented for the DS/FH TT＆C system under jamming conditions. This method can evaluate the anti-jamming performance more effectively and comprehensively. Taking three classical interfer- ence environments as example, i.e. tone jamming, pulse interference and highly dynamic condition, the effects of different jammings on MPC with varying parameters are investigated. To overcome the deficiencies such as too many steps, poor efficiency and high cost in the anti-jamming capability test, the testing order of the attributes is modeled as an optimal route problem using Ant Colony Opti- mization （ACO） algorithm. Simulation results show that the proposed analytical model is correct and effective. The conclusions are evaluated to be significant and referable for the choice of DS/FH TT＆=C system jamming test schemes.
