摘　　要：防空警戒雷达检测概率是防空警戒雷达效能评估的重要指标之一。本文通过对雷达检测概率特性的分析,给出了无干扰情况下防空警戒雷达对空中运动目标检测概率的计算方法和数学模型,然后进一步探讨了自卫干扰和远距离支援干扰情况下防空警戒雷达对空中运动目标检测概率的数学模型,为定量评估防空警戒雷达干扰效果提供了一种新的方法。Detection probability is one of the important indexes for evaluating the performance of air- defense warning radar. The characteristics of detection probability of air- defense warning radar are analyzed. Then, the calculation method and mathematic models of detection probability of the air - defense warning radar when it irradiate the air maneuvering target with one frequency, respectively under no - jamming condition, self - defense jamming condition, and far support jamming condition, are discussed. Thus a new method is provided for evaluating air - defense warning radar jamming.
