精密激光测距弱小回波信号自适应滤波方法
Adaptive Filtering Method for Weak Echo Signal in Precision Laser Ranging
摘要
Abstract
Due to the presence of a large amount of noise in the laser ranging signal,the accuracy of precision laser ranging is reduced.Therefore,an adaptive filtering method for weak echo signals in precision laser ranging is pro-posed.Based on the construction of a weak echo signal reception model,calculate noise evaluation indicators and develop an adaptive filtering program.By applying the Lagrange multiplier method,parameter optimization rules are formulated and the optimal adaptive filtering parameters are determined.And those parameters are substituted into the adaptive filtering program to obtain accurate weak echo signals,achieving the goal of accurate ranging.The experimental results show that this method has good application performance.关键词
