机载相控阵雷达过高的辐射能量威胁了战斗机的生存能力。为了减少相控阵雷达搜索模式辐射能量,提出了基于辐射能量控制的搜索模型。将总能量消耗函数和检测概率相对误差作为目标函数,以平均功率、波束宽度、积累脉冲数以及脉冲重复间隔作为优化变量,选取非支配遗传排序算法对此模型进行优化。仿真结果表明,在同样检测概率情况下,提出的搜索方法可以有效控制雷达辐射能量,具有更好的射频隐身性能。
Airborne phased array radar radiation energy is too high threat to the fighter’s viability. In order to reduce the radiation energy of the phased array radar search pattern, a search model based on radiant energy control is proposed. Taking the relative error between the total energy consumption and the detection probability as the objective function, the average power, the beam width, the number of accumulated pulses and the pulse repetition interval are taken as optimization variables. The non-dominant genetic algorithm is chosen to optimize this model. The simulation results show that under the same detection probability, the proposed search method can effectively control the radiation energy of the radar and has better performance of stealth radio.
