噪声调频干扰对地面PD雷达目标探测能力的影响

Influence of Noise FM Jamming on The Target Detection Ability of Ground-based PD Radar

分析了地面脉冲多普勒(PD)雷达系统组成和工作特点,论述了该雷达在杂波重叠环境中采用参差PRF组和3/7准则解模糊后对目标的探测能力,同时与其在存在干扰重叠的噪声调频干扰环境中对目标的探测能力进行了对比,得到了该干扰信号对雷达目标探测能力的影响。

This paper analyzes the system composition and operating characteristics of ground-based pulsed doppler（PD） radar,discusses the detection ability of the radar in the environment of clutter overlap after resolving ambiguity by means of stagger pulse repetition frequency（PRF） group and 3/7 principle,at the same time compares the target detecting ability with that of the radar in the environment of noise frequency modulation（FM） jamming with jamming overlap, and gains the influence of such jamming signal on radar target detection ability.
