The invention relates to a method and a system for generating dual excitation signals. The method includes generating two channels of second intermediate-frequency signals, and subjecting the two channels of second intermediate-frequency signals to up-conversion processing so as to obtain two channels of first intermediate-frequency signals; generating at least one standard-frequency signal and selecting a target standard-frequency signal from the standard-frequency signals according to a preset operating mode; generating a broadband signal, generating a modulating signal according to the standard-frequency signal and the broadband signal, and subjecting the modulating signal to corresponding processing according to a preset operating mode so as to obtain a local oscillation signal; subjecting each of the two channels of first intermediate-frequency signals and the local oscillation signal to up-conversion processing to obtain two channels of excitation signals, and controlling the two channels of excitation
