雷达帧周期1ms,在7.5km有一瑞利杂波,且15km处有一点目标，仿真该雷达的恒虚警处理-Radar frame period 1ms, in a Rayleigh clutter 7.5km and 15km at a little target, simulation of the radar' s CFAR

在雷达信号检测中，当外界干扰强度变化时，雷达能自动调整其灵敏度，使雷达的虚警概率保持不变。具有这种特性的接收机称为恒虚警接收机。(In radar signal detection, the radar can automatically adjust its sensitivity when the external interference intensity changes, so that the radar's false alarm probability remains uncha
