[0041] Set the emission pulse as a high-frequency laser pulse with a fixed frequency, its wavelength λ=1.55μm, the difference between the emission pulse and the local oscillator frequency, namely f 1 It is 81.5MHz, assuming that the frequency shift of 1MHz is generated due to the influence of wind speed after the transmission pulse is transmitted, so the center frequency f after the down-conversion of the reception pulse is 2 It is 82.5MHz, that is, △f=f 2 -f 1 =82.5-81.5=1MHz, the wind speed is In order to verify the effectiveness of the algorithm proposed by the present invention, a sine signal with a frequency of 82.5 MHz is simulated to represent the echo pulse signal after down-conversion. In order to simulate the real detection environment, Gaussian noise is added to the pulse signal, and the signal Sampling frequency is 400MHz, after sampling, carry out center frequency with traditional method and the method that the present invention proposes respectively to seek, a...
