摘　　要：雷达的一个重要指标是雷达探测目标的距离,采用表示平均单个脉冲信噪比和接收机匹配损耗对检测距离的影响的检测因子,可使检测距离的计算过程简化,由此建立的干扰条件下雷达作用距离的数学模型,可对自卫干扰和远距离支援干扰同时存在情况进行干扰距离的计算,并可分析雷达采用反干扰措施如低旁瓣、频率捷变对雷达检测距离提高的效能。An important parameter of radar is the radar detection range. The detection factor, which represents the influence of single pulse averaged signal-to-noise ratio and receiver matching loss on detection range, can simplify the detection range computation. The model of radar detection range in jamming circumstance can compute the jamming range when self-screening jamming and stand-off jamming occur at the same time, and can analyze the efficiency of radar counter-counter measure（RCCM） to improve detection range.
