摘　　要：为了解决当前激光雷达信号出现错误识别结果概率高的难题,设计了一种复杂环境下激光雷达信号的模式识别技术。首先将激光雷达信号识别看作为是模式识别中的一个多分类问题,然后从信号提取分类特征,最后引入模式识别技术对激光雷达信号进行建模与识别,并在Matlab 2017平台上进行了激光雷达信号识别仿真实验,结果表明,激光雷达信号正确识别率超过92%,激光雷达信号识别的时间缩短为11.87 ms,识别整体效果明显好于传统方法,具有十分广泛的应用前景。In order to solve the problem of high probability of error recognition results of lidar signals,a pattern recognition technology of lidar signals in complex environment is designed.Firstly,the recognition of lidar signal is regarded as a multi-classification problem in pattern recognition.Then,the classification features are extracted from the signal.Finally,the pattern recognition technology is introduced to model and recognize the lidar signal.The simulation experiment of lidar signal recognition is carried out on 2017 platform.The results show that the correct recognition rate of lidar signal of this technology is more than 92%,and the time of lidar signal recognition is 11.87 ms.The overall effect of lidar signal recognition is obviously better than that of traditional methods,which has a very wide application prospect.
