摘要 鉴于飞机尾流具有独特的多普勒及空间分布特性和较强的雷达可探测性,对降雨条件下飞机尾流的雷达特性进行了研究.基于雨滴参数和尾流速度场模型,建立尾流中雨滴的运动方程,然后数值求解该方程得到了尾流中雨滴数密度分布特性.在此基础上,基于某典型W波段雷达参数,通过信号处理得到了降雨条件下飞机尾流的雷达回波,并发现了其独特的多普勒特性.这为航空安全和反隐身中尾流探测方法研究提供了重要的理论指导. Considering that the aircraft wake is of specific Doppler and its spatial distribution features, and favorable detectability of radars, this paper deliberates the radar characteristics for aircraft wake under the rainfall. In terms of the models for raindrop parameters and wake velocity field, the motion equation of raindrop in the wake is established, and then this equation is numerically solved, thus obtaining the density distribution of raindrop number in the wake, based on which, the radar echo of aircraft wake under the rainfall can be achieved by signal processing, in terms of the parameters of a certain typical radar in W band, and the specific Doppler characteristics are found in this paper. It brings about a significant theoretical guidance for the method study of the wake detection on air safety and anti-stealth.
