The application of the Morlet wavelet on response filtering of the helicopter cannon's recoil

摘要

The Morlet wavelet is a complex-exponential function with gauss function wave . Making use of the frequency character of "bell shape", the paper presented the response filtering method of the helicopter cannon's recoil and ensured that the phase did not distort after filtering. The paper studied the validity of the way through the numerical simulation. The project application indicated that the method could get rid of the noise of the recoil response effectively and had great application potential on the dynamic loading identification of the helicopter cannons.
