摘　　要：介绍了一种利用小波模极大值检测光纤陀螺干扰信号的方法。对实测的光纤陀螺干扰信号采用连续小波变换,通过分析小波变换模极大值线的特点,提出了光纤陀螺扰动信号探测的小波模极大值线方法,并进行了实验验证。结果表明:小波模极大值方法能够有效的对光纤陀螺干扰信号进行检测和定位。A method of FOG interference signal detection by using wavelet modulus maxima is introduced.Through continuous wavelet transform by use of actual measured FOG interference signal and the analysis of modulus maxima line,a method of FOG interference signal detection based on wavelet modulus maxima method was proposed.Experimental verification was carried out.It can be concluded that wavelet modulus maxima method detects and locates effectively the FOG interference signal.
