摘　　要：从噪声干扰的原理出发,详细地分析了噪声干扰信号的产生并推导出干扰条件下的雷达最大作用距离的求解公式。仿真了目标和干扰机接收的信号强度随距离而变化的特征以及干扰有效辐射功率密度对雷达探测能力影响的相对效果。The features of noise jamming and formation are discussed on the basis of noise jamming principle. Radar maximal operation range under noise jamming is introduced in logarithm method. The faature of the variation of the amplitude of signals received by target and jammer with range,the effect of effective radiated power density on the detection ability of radar are simulated.
