Therefore,in order to garantee a certain level of probability of detection,the constant false alarm rate method is applied.
在雷达信号检测系统中,对于一定的检测门限,如果噪声或杂波电平增大一点,虚警率便会大大增加,同时使发现概率降低,这样便降低了雷达系统发现目标的能力,因此在现代雷达信号检测系统中,为了保证一定的发现概率,一般采取恒虚警率(CFAR)处理,在雷达系统进行恒虚警处理时,由于杂波强度可能偏离统计平均值而产生起伏,此时采用理论的门限判决系数将使虚警率大大增加。
