摘　　要：恒虚警(CFAR)检测是雷达信号处理的重要组成部分。介绍了某型雷达的目标检测原理,分析了噪声恒虚警处理中门限系数对目标检测的影响,提出了一种基于噪声采样的门限系数确定方法,最后在仿真计算的基础上验证了该方法的可行性。The constant false alarm rate（CFAR） detection of radar signal plays an important role in radar signal processing. The principle of object detection of a certain radar is introduced, the influence of threshold coefficient on object detection is analysed, and a method to determin the threshold coefficient based on noise sampling is proposed. Finally, the feasibility of the method is verified through simulation.
