Noise source test method, computer equipment and noise source test system

The invention discloses a noise source test method, computer equipment and a noise source test system. The method comprises the steps of performing excitation operation on a target object, and obtaining original test data corresponding to at least two original noise sources in the target object; processing the original test data corresponding to each original noise source to obtain a total noise function corresponding to each original noise source; performing time-frequency analysis on the total noise function corresponding to each original noise source to obtain noise contribution corresponding to each original noise source; and based on the noise contribution amounts corresponding to the at least two original noise sources, analyzing the at least two original noise sources, and determining a main noise source of the target object. According to the method, the main noise source of the target object can be determined without complex operation and hardware equipment, the method is convenient and rapid, quantit
