本文探讨与分析了旋转调谐磁控管的频率分布律由经典的反正弦分布改变为均匀分布后抗干扰性能的提高与得益:在保持干扰带宽不变的条件下,干扰概率(即雷达受干扰的概率)将下降;在保持干扰概率不变的情况下,将迫使干扰机展宽干扰带宽,并使干扰功率密度下降。文内对频率分布律、干扰概率及其变化、干扰带宽的展宽以及干扰功率密度的下降作了分析和推证,并给出最终的数学模型和曲线。
This article explores and analyzes the improvement and benefit of the anti-jamming performance of the rotating tuning magnetron when the frequency distribution law is changed from the classic arc sine distribution to the even distribution: under the condition of keeping the interference bandwidth constant, the interference probability The probability of interference will drop; while keeping the probability of interference unchanged, the jammer will be forced to widen the interference bandwidth and reduce the interference power density. The paper analyzes and concludes the frequency distribution law, the interference probability and its variation, the broadening of the interference bandwidth and the decrease of the interference power density, and gives the final mathematical model and curve.
