针对激光雷达传输频率不稳定现象,提出激光雷达通信传输频率线性代数模型优化方法,降低激光雷达通信传输频率的漂移、有效抑制通信噪声。基于激光雷达稳频装置的通信传输稳频控制原理,为优化装置中控制系统发生搅动时产生的通信传输频率漂移,将频率响应初始斜率和频率响应截线斜率作为线性输入建立线性代数方程组,并求解该方程组,获取最低频率,以此完成控制系统在搅动时的频率稳定优化。测试结果表明:该方法应用后,激光雷达在通信传输过程中产生的频率漂移降低,通信传输频率稳定,激光雷达通信传输噪声抑制性能提升,激光雷达通信信号切换稳定性较高,应用性能较好。
Aiming at instability of lidar transmission frequency,a linear algebraic model optimization method of lidar communication transmission frequency is proposed to reduce the drift of lidar communication transmission frequency and effectively suppress communication noise.Based on the control principle of communication transmission frequency stabilization of lidar frequency stabilization device,in order to optimize communication transmission frequency drift when the control system in device is agitated,the initial slope of frequency response and the slope of frequency response section line are taken as linear inputs to establish linear algebraic equations,and the equations are solved to obtain the lowest frequency,so as to complete optimization of frequency stabilization of control system when control system is agitated.The test results show that:after the application of this method,the frequency drift of lidar in the process of communication transmission is reduced,the communication transmission frequency is stable,the noise suppression performance of lidar communication transmission is improved,the switching stability of lidar communication signal is higher,and the application performance is better.
