摘要
为提高传感器的检测性能,将一种经典的恒虚警率检测器CA-CFAR与多传感器集中式检测相结合。给出了多传感器集中式CA-CFAR检测器在均匀杂波环境中的虚警概率解析表达式。对两传感器集中式恒虚警率检测器和三传感器集中式恒虚警率检测器的检测概率进行了仿真,仿真结果表明,多传感器集中式恒虚警率检测器相对于单传感器恒虚警率检测器的检测概率有明显提高。
To improve the performance of sensor detection, one classic CFAR detector CA-CFAR is combined with multi-sensor centralized detection. The analytic expression of multi-sensor centralized CA-CFAR detector＇s false alarm probability in homogeneous clutter environment is derived. The detection probability of two-sensor centrali-zed CFAR detector and three-sensor centralized CFAR detector are simulated, the result of simulation indicates that the multi-sensor centralized CFAR detector is obviously advanced in terms of performance, compared with the single sensor CFAR detector.
