Method of signal processing of coil target based on wavelet analysis

A new method based on wavelet of finding the point of bullet flying across the coil is introduced. The point of bullet flying across the coil decides velocity of flying object directly, so finding this point accurately is very important, wavelet method is introduced in the new method. The influences of noise adding and zero excursion to coil are reduced by use this way. The anti-jamming ability of velocity measurement system is improved finally.
