摘　　要：针对线性调频连续波雷达目标检测问题,提出了一种多门限联合检测方法。该方法考虑了连续波雷达回波噪声基底随环境变化的特点,并通过统计实测数据,利用恒虚警门限和多个固定门限相结合的方法抑制噪声尖峰产生的虚警。实测数据表明,该方法能够在略微降低检测概率的同时极大地降低虚警概率。This paper presents a joint multi-threshold detection method for LFMCW radar target detection.The proposed detection method takes into account the varying of CW radar echo noise floor with environment.In addition,the method can suppress the false alarm caused by noise spikes by using CFAR threshold and multiple fixed thresholds,which stems from statistical analysis of measured data.The test results show that the proposed detection method can reduce the radar false alarm probability greatly with slight detection probability loss.
