Abstract

In the flight test of a helicopter model, aiming at the problem that the output signal of the fiber optic gyroscope HB300 mixed with spike noise and random noise affects the data analysis, a data processing method based on wavelet transform filtering is proposed to extract the effective overload signal of the helicopter. The comparison shows that the filtered data is in good agreement with the on-board bus signal. This method can separate the characteristic parameters of the useful signal, suppress the output of noise, and meet the needs of engineering test data analysis. At present, the method has been applied in the data processing of a certain helicopter model engineering test, and the signal-to-noise ratio of the output signal of the fiber optic gyroscope HB300 is improved.
