【摘要】 激光测距机模拟信号处理器不能利用多个脉冲之间的相关信息 ,所以目标检测能力有限。而激光测距机数字信号处理器可以利用多个脉冲之间的相关信息。目标匹配和跟踪算法利用多个脉冲之间的相关信息 ,降低了目标检测门限 ,提高了测距范围。就该算法对目标检测的虚警概率和检测概率进行了分析 ,证明了该算法的有效性。更多还原

【Abstract】 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.更多还原
