摘　　要：电子战环境中,被探测目标具有释放干扰躲避雷达探测的能力。弹载雷达不仅要在杂波环境中优化发射信号以提高波形抑制杂波的能力,同时还应考虑雷达与目标相互间的博弈。本文建立弹载雷达与拥有干扰能力的目标间对抗时的信号模型,基于最小均方误差准则二次分配雷达发射波形能量,优化设计雷达发射波形,初步解决了杂波背景中弹载雷达受到目标施放干扰而导致的雷达探测性能降低的问题。仿真结果表明,二次优化对噪声、杂波和干扰影响的抑制效果为单次优化的3倍。In the electronic warfare environment, the target can release interference to avoid radar detection. The missile-borne radar needs to optimize transmitting signal to improve the ability of clutter suppression. Otherwise, the interaction between the radar and target is also a problem. The confrontation signal model between missile-borne radar and target that have jamming ability is established. Based on MMSE, the radar transmitting waveform energy is distributed twice to optimize transmitting waveform. The radar detection perl＇ormance reduction problem caused by interaction between the radar and jammer is solved preliminarily. The simulation results show that the effect of twice optimization on noise, clutter and interference is three times that of single optimization.
