1/f类噪声是光学陀螺信号中的主要误差源,研究仿真生成这类信号的方法对分析光学陀螺的输出信号具有重要意义.基于常用的FFT和小波生成方法,考虑到这两种方法的特点和不足之处,提出了将两者结合来生成1/f类信号的新方法.与目前性能最好的小波方法相比,新方法不仅具有其优点,即可生成具有任意谱指数的1/f信号,而且,从所生成1/f信号的功率谱密度和Allan方差两方面进行比较,新方法的性能优于小波方法. 1 / f type noise is the main source of error in optical gyroscopes, and it is of great significance to study how to generate such signals by simulation.According to the commonly used methods of FFT and wavelet generation, Characteristics and shortcomings, a new method is proposed to combine the two to generate 1 / f signals.Compared with the best wavelet method, the new method not only has its advantages, but also can generate 1 / f signal, and the power spectrum density and Allan variance of the generated 1 / f signal are compared. The performance of the new method is better than the wavelet method.
