为了提高激光接收器的精度,解决传统方法存在缺陷,提出激光接收器的抖动抑制优化控制方法。首先采用闭环抖动控制方案对激光接收器的机抖频率和幅度实施控制,通过抖动幅度闭环控制器采用自动幅度控制环路控制抖动,依据抖动的正弦波幅度调整形式注入随机抖动,然后融入抖动随机噪声,过滤掉激光接收器的动态锁区,提出了噪声注入的优化方法,给出优化后噪声注入压缩动态锁区方案,解除激光接收器动态锁区,最后对激光接收器的抖动进行有效抑制。实验结果表明,该方法的激光接收器具有较高抖动抑制能力。
In order to improve the accuracy of the laser receiver and solve the shortcomings of the traditional methods, an optimal control method for the jitter suppression of the laser receiver is proposed. First, the closed-loop dithering control scheme is used to control the frequency and amplitude of the laser receiver’s jitter. The jitter amplitude closed-loop controller uses automatic amplitude control loop to control the jitter. The random jitter is injected according to the jitter sine wave amplitude adjustment. Noise, filter out the dynamic lock area of the laser receiver, put forward the optimization method of noise injection, give the scheme of injecting compressed dynamic lock area after noise optimization, release the dynamic lock area of the laser receiver, and finally effectively suppress the jitter of the laser receiver . Experimental results show that the method of laser receiver with high jitter suppression.
