本文叙述和分折脉冲多卜勒雷达受限于低高度的原因,并以设计实例给出简捷的计算方法。一、脉冲多卜勒雷达存在最小起量高度的原因在脉冲多卜勒雷达中,为了消除直达信号的有害影响,在辐射信号时,接收机是封闭的。雷达在很低的高度工作时,由于回波延 This paper describes and points out the reasons why the impulsive Doppler radar is limited to low altitude, and gives a simple calculation method based on the design example. First, the pulse Doppler radar there is a minimum allowable height of the reason In pulsed Doppler radar, in order to eliminate the harmful effects of direct signals, the receiver is closed when the radiation signal. Radar works at very low altitude due to echo delays
