The invention belongs to the technical field of signal processing, relates to a radio signal carrier frequency estimation method based on a generalized cyclic correlation entropy and is used for solving the problem of estimating radio signal carrier frequency in radio signal monitoring. The method includes: utilizing a known signal to respectively calculate a correlation function of the signal in European space and correlation entropy of the signal in Hilbert space; when the known signal has second-order cyclic stable characteristics, acquiring a composite correlation entropy based on limited European space and Hilberty space; calculating the generalized cyclic correlation entropy of the known signal, establishing a three-dimensional stereogram, and acquiring carrier frequency of an original signal through frequency spectrum peak. By the method, robustness to pulse noise, Gaussian noise and noising mixing the two can be improved, and higher-accuracy radio signal carrier frequency estimation can be realized.
