To eliminate dynamic lock-in error of mechanically dithered ring laser gyroscope, it is desirable to inject a pseudo smooth random noise into the sine wave dither signal, and the dither amplitude is stochastic, so it can eliminate dynamic lock-in error by time domain average. 为了消除抖动偏频激光陀螺仪的动态闭锁误差,需要向正弦抖动信号中注入具有平稳性的随机噪声,以使抖动幅度随机变化,从而可以通过时域平均来消除动态闭锁误差。
With the comparison of the equivalent design, the proposed HFCG has lower power consumption, faster lock-in time and a smaller die area. 比同档次设计具有更小的芯片面积、更低的功耗和更短的锁定时间,达到了较高的性能指标。
A kind of frequency tracking algorithm was proposed, which uses an adaptive search step, can achieve fast lock-in time. 本文提出了一种自适应搜索步长频率捕获算法可以达到环路快速锁定。
