摘　　要：相控阵雷达可通过合理配置工作参数优化其性能。针对相控阵雷达在搜索目标时易受敌方电子侦察设备威胁的现实,研究了在保持搜索能力的同时,通过合理配置参数降低截获概率的问题。分析了影响相控阵雷达搜索状态LPI(Low Probability of Intercept)性能的主要因素,建立了截获概率模型与搜索能力模型,给出了3种参数调整策略。仿真试验验证了模型的有效性,并比较了3种策略的优劣。The phased array radar could optimize its performance through appropriate scheming work parameters. Aim at the fact that the phased array radar is easily threatened by the enemy's electro-detector when working in search state, the problem that through configuring reasonable parameter to reduce the probability of intercept while holding the ability of search is studied. The main factors which influence the phased array radar's LPI capability in search state are analyzed. The probability of intercept mode and the ability of search mode is built up,and then three strategies to configure parameter is put forward. The effectiveness of the mode and the characteristic of these strategies are validated by the simulation results.
