摘　　要：为了解决机载雷达LPI性能无法定量评估的问题,提出了无源定位暴露区的概念。首先建立了无源定位暴露区的数学模型,其次推导了机载雷达在采取不同LPI措施下的无源定位暴露区,最后通过仿真实验,对比分析了机载雷达采取LPI措施前后,无源定位暴露区的缩减情况。仿真结果表明机载雷达采取低副瓣天线、功率控制以及LPI波形后,无源定位暴露区可缩减30%以上,可有效降低被多站无源定位的概率。In order to solve the problem that LPI performance of airborne radar cannot be quantitatively evaluated,the con⁃cept of passive location exposure area is proposed.Firstly,the mathematical model of passive location exposed area is established.Secondly,the passive location exposed area of airborne radar under different LPI measures is deduced.Finally,through simulation experiments,the reduction of passive location exposed area of airborne radar before and after LPI measures are compared and ana⁃lyzed.The simulation results show that after airborne radar adopts low sidelobe antenna,power control and LPI waveform,the expo⁃sure area of passive location can be reduced by more than 30%,which can effectively reduce the probability of passive location by multiple stations.
