摘　　要：相控阵雷达可通过合理配置工作参数优化其性能。针对雷达在电子对抗环境中需要具备低截获概率(low probability of intercept,LPI)的要求,从低截获原理出发,对两种辐射能量控制策略:最小功率策略和最小驻留策略的实现方法进行了理论推导。在此基础上,建立以检测概率为目标的探测性能优化模型,并给出了两种能量控制策略下的最优辐射控制方案。The performance of a phased array radar could be optimized by allocating working parameters appropriately. In order to satisfy the requirement of low probability of intercept （LPI） for radar when using in the electronic countermine environment, some theoretic derivations are given according to LPI principle on two radiation power controlling strategies, which includes the minimum power strategy （MPS） and the minimum dwell-time strategy （MDS）. Then a detecting performance optimization model aiming at detecting probability is put forward. And at the same time, the optimal radiation control scheme from the two power controlling strate gies can be obtained.
