摘要
高精度光纤陀螺是导航与制导系统的主要组成部分.采用基于数字信号调制解调技术对光纤陀螺进行闭环控制可以有效地提高光纤陀螺的精度.对光纤陀螺原理及信号检测方法进行了大量的研究和实验,以高速数字信号处理芯片TMS320F2812为基础,研制成功了基于阶梯波调制技术的闭环光纤陀螺全数字式信号检测系统,并给出了性能及测试结果.
High precision FOG is the important part of navigation and guidance system. The closed-loop control based on digital modulating and demodulating technique can greatly improve the precision of FOG. The principle and signal detection method of FOG are studied and experimented. On the basis of TMS320F2812, the digital closed-loop detecting system of FOG is successfully developed with the step wave modulating technology. Finally the performance and results of tests are given.
