摘　　要：目标探测是雷达的一项重要功能,由于杂波和噪声一般在目标回波的距离和多普勒维同时存在,如果只使用一维恒虚警率检测将会降低探测性能,因此需要二维恒虚警率进行目标检测。传统的二维恒虚警率检测会使计算量大大增加,影响目标探测的实时性。改进的二维恒虚警率检测方法可极大减少检测单元,从而缩短了目标检测时间,并经过了工程验证。Target detection is an important function of radar.The clutter and noise in distance and Doppler dimension of the target echo exist at the same time,if you only use one-dimensional constant false alarm rate(CFAR)detection,the detection performance will be reduced,so the 2DCFAR is required for target detection.The traditional 2D-CFAR detection will greatly increase the calculation quantity,affect the timeliness of target detection.The improved 2D-CFAR method can greatly reduce the detection units and shorten the target detection time,and has been verified through engineering.
