摘要
随着现代电子战技术的发展,机载雷达面临的战场环境日趋复杂。传统机载雷达往往发射固定的波形,很难在复杂多变的电磁环境和动态时变杂波的环境下有效完成目标的检测和跟踪任务。以认知雷达和多输入多输出(multiple-input multiple-output,MIMO)雷达为代表的新体制雷达,通过发射端灵活设计与环境相匹配的波形,提升了机载雷达在复杂战场环境下的适应能力。对新体制机载雷达波形优化设计的研究与发展进行了综述。首先,系统阐述了认知雷达的基本原理,并概述了新体制机载雷达波形优化设计;然后,分别从先验条件和收发处理的角度对新体制机载雷达波形优化设计的研究成果进行了梳理;最后,针对当前机载雷达波形优化技术存在的问题,对未来新体制机载雷达波形优化设计的发展趋势进行了展望。
With the development of modern electronic warfare technology,the battlefield environment faced by airborne radar is becoming more complex.Traditional airborne radar often transmits fixed waveforms,which make it more difficult to effectively detect and track the target in the complex and changeable electromagnetic environment and the dynamic time-varying clutter environment.The new system radar,such as cognitive radar and multiple-input multiple-output(MIMO)radar,can flexibly design waveforms at the transmitter to coincide with the environment,which improves the adaptability of the airborne radar in the complex battlefield environment.This paper summarizes the research and development of waveform optimization design for new system airborne radar.Firstly,the basic principle of cognitive radar is systematically described,and the waveform optimization design of the new system airborne radar is summarized.Then,the research results of waveform optimization design of new system airborne radar are combed from the perspective of the prior condition and transmit-receive processing.Finally,aiming at the problems that existed in the current airborne radar waveform optimization technology,the development trend of airborne radar waveform optimization design in the future is proposed.
