Research on automatic recognition and processing method for mobile vehicles interference in geomagnetic second sampling observation based on the wavelet transformation
In order to improve the processing and extraction efficiency of mobile vehicle interference in geomagnetic second data,a set of automatic recognition and processing methods for mobile vehicle interference was designed based on wavelet transform.The interference data from Liyang and Hechi stations were analyzed and studied.The results show that selecting db6 wavelet,db9 wavelet,and sym8 wavelet to identify and extract moving vehicle interference can achieve a maximum recognition rate of over 91%and a maximum accuracy rate of over 83%.
