摘要

A spectral method is proposed to determine the signal frequency and readings of a laser radar with a frequency modulation of the reference channel based on signal preprocessing with a Gaussian window and calculation of its spectral centroid. Numerical simulation and experiments with a frequency modulation band 5-20 MHz wide have shown that this method provides an order of magnitude better accuracy than the conventional spectral analysis methods.
