分析了基于截获因子模型的有源相控阵雷达辐射功率控制原理,提出了雷达实现低截获的最小功率控制策略。基于运动目标探测性能与隐身性能约束下的目标探测最优化,分析了雷达驻留时间等控制参数对探测性能的影响,给出了控制参数的优化模型,得出了满足隐身要求下相控阵雷达的最优控制。理论分析和仿真验证了功率控制策略的合理性和最优控制参数选择的有效性。

Based on intercepted radiation power control for active phased array radar principle, minimal power control strategy is proposed for a low interception radar. Influence of control parameters to detection ability is analysed based on moving target detec- tion and optimization under restriction of steahy ability, optimization model is given of control parameter and optimization control of phased array radar is achieved for meeting steahy restriction. Principle analysis and experimental verification of simulation shows that power control strategy of the rationality and feasibility of implementation.
