Detecting probability and false alarming rate study of digital signal processor of laser ranger

The analogical signal processor of the laser ranger can not make use of the interrelated information between pulses. Therefore,checking the target is limited. The digital signal processor of the laser ranger can make use of the interrelated information between pulses. The target matching and tracking algorithm makes use of the interrelated information,decreases the threshold and increases the range. This paper studies the false alarming rate and detecting probability and proves that this algorithm is effective.
