类似于我圈出来的。
在空旷地区,时变增益设置为60-80db,8MS间隔。当75PVC位于4米以上时,就会出现虚警,且恒定滞后实警(目标物)约1米的TOF。幅度约为实警的0.4倍。
Something like that.
In open areas, time-varying gain is set to 60-80db and 8MS interval.When the 75PVC is located at more than 4 meters, the false alarm will appear, and the TOF of the real alarm (target object) is about 1 meter with a constant lag.The amplitude is about 0.4 times of the real alarm.
