This paper researched the time-frequency characteristics of the radar emitter signal such as components' physics meaning and restraining mutual interferences of the multi-component,based on the local wave decomposition.Abstracted the instantaneous frequency features and wave features.Simulation experiments show that this method has better characteristics on the restraining mutual interferences of multi-components,improving frequency resolution and localized time-frequency of signals than tradition methods.It is new method for the feature analysis of radar emitter signals.
