本文回顾了战场侦察雷达的原理,以锯齿和对称三角波调频雷达为例,叙述了其原理和参数。从理论上分析了这种雷达被干扰的机理,并对其距离拖引加杂波干扰、锯齿调相频移干扰和正弦波调相干扰产生的多目标速度欺骗干扰进行了数学分析。文章还指出这种新出现的雷达的干扰应给以重视。
This paper reviews the principle of battlefield reconnaissance radar, and illustrates its principle and parameters with sawtooth and symmetrical triangular wave frequency-modulated radar. The mechanism of such radar jamming is analyzed in theory. The mathematic analysis of multi-target speed spoofing jamming caused by dragging plus clutter jamming, sawtooth phase-shifting jamming and sinusoidal phase modulation jamming is analyzed. The article also pointed out that the interference of this emerging radar should be given priority.
