摘　　要：现代战场电磁环境日趋复杂,末端主动制导阶段弹载雷达常受到噪声、杂波和干扰影响从而导致弹载雷达的目标检测、识别及跟踪性能下降。现有弹载雷达波形较为固定,没有根据战场环境改变自身参数的能力,严重制约导弹制导精度。针对电子战环境中的弹载雷达波型设计问题,在分析影响弹载雷达性能因素基础上,分析了弹载雷达常用信号,给出了三种干扰条件下弹载雷达波形设计方法。最后探讨了目前弹载雷达波形设计存在的问题及今后的研究方向。The modern battlefield electromagnetic environment is becoming increasingly complex.The missile-borne radar on terminal guidance phase is often affected by noise,clutter and jamming,which leads to a decrease in performance of target detection,recognition and tracking. The waveform of existing missile-borne radar is fixed relatively,and it can not be changed according to the battlefield environment,so the guidance precision of missile is seriously restricted. For the missile-borne radar waveform design problem,based on the factors which influence the performance of missile-borne radar,three kinds of missile-borne radar waveform design methods under jamming conditions are summarized,and the existing problems and the future research direction of waveform design are discussed.
