摘　　要：针对脉冲型半导体激光测距系统,提出了一种卡尔曼滤波与最小均方差滤波相结合的非线性滤波算法,对测距系统的回波信号进行滤波分析。结果表明,采用所提出的非线性滤波算法对实验数据进行处理,可将精度最高提高2.1 m,同时使误差降低65.63%。A nonlinear filtering algorithm based on the combination of Kalman filtering and minimum mean square error filtering is proposed for the pulsed semiconductor laser ranging system, and the echo signal of ranging system is filtered and analyzed. The results show that the accuracy can be improved to 2.1 m, and the error reduces by 65.63% when using the proposed nonlinear filtering algorithm to deal with the experimental data.
