随机噪音对LG输出特性的影响

Influence of Random Noise on Output of Laser Gyro

利用均值计算了随机噪音对陀螺输出的影响.结果表明:随机噪音激励强度越大,均值与理想值偏差越小;但随机过程的分散性变大,输出信号变宽.依靠调幅加噪的方法给陀螺进行加噪,并按照特定的测试装置图对全反射棱镜式激光陀螺(TRPLG)的静态功能进行了检测,最终找到了TRP激光陀螺的最佳加噪噪音强度值.

Random noise influences is calculated using relational medial knowledge to laser gyro. The results show that the bigger invigorative strength from random noise is, the warp smaller from medial value with ideal will be; but with the increase of the dispersion of the random process,outputting signal becomes wider. The noise is added depending on the principle that amplitude modulation,and the result is detected making use of the TRPLG static state test installation. The best noise strength value to TRP laser gyro is given.
