| 摘 要： | 集成光学陀螺的输出信号叠加了多种噪声成分,干扰了有用信息的检测.根据集成光学陀螺输出信号的特点,提出了一种在高速数字信号处理器组成的数字系统中,利用数字滤波器及互相关理论,对集成光学陀螺的含噪声信号进行处理的方法.结果表明在信噪比为10 dB的情况下,该技术可以将信号误差基本控制在3%以下,实现了复杂噪声环境下集成光学陀螺系统信号的检测.

| Abstract: | The output signal of integrated optic gyroscope(IOG)is mixed up with many sorts of noises.It is difficult to detect exactly the signal with many sorts of noises. According to the characteristics of output signal from detector, a signal processing method for the IOG is introduced,which detects signal from noise by taking advantage of digital filter and cross-correlation, based on a digital system comprised of a high-performance digital signal processor.The result of experiments show that percent error is les... |
