In this paper, a kind of digital lockin amplifier used in FOGsignal detection is designed.
提出了一种用于光纤陀螺信号检测的数字锁相放大器的设计方法。

But, the FOG precision developed in China is generally lower also the GPS has the congenital flaw which signal can be disturbed.
但目前国内光纤陀螺精度普遍较低而GPS又有信号易受干扰的先天缺陷。

Based on the analysis to signal detection theory of FOG, the analog demodulation circuit and digital logic circuit etc were designed, and prototype test was carried out.
