雷达抗干扰能力是军用雷达最重要的性能之一,但迄今还没有通用的度量方法。本文首先评价了前人的有关论述,又分析了决定雷达抗干扰能力的各项因子,它们是:雷达平均发射功率P、雷达对目标的观察时间T_O、雷达的瞬时带宽B_I、雷达的天线增益G、雷达的天线质量因子F_A与雷达的信号质量因子F_S,最后提出这些因子的乘积可作为综合度量雷达抗干扰能力的表达式。
Radar anti-jamming capability is one of the most important performance of military radar, but so far there is no common method of measurement. This paper first evaluates the previous expositions and analyzes the factors that determine the anti-jamming capability of the radar. They are: the average radar transmit power P, the radar observation time T_O, the instantaneous bandwidth B_I of the radar, the antenna gain of the radar G, the radar antenna quality factor F_A and the radar signal quality factor F_S. Finally, the product of these factors can be used as an integrated measure of the radar anti-interference ability.
