Abstract Specific emitter identification is the key research fields of modern electronic intelligence systems and electronic support measurement systems. Based on the analysis of individual features of radar emitter, a specific emitter identification algorithm is proposed based on ambiguity function. Considering the redundancy of ambiguity function, the slices of ambiguity function and localized ambiguity function are used to represent the individual features, such as pulse envelope, phase noise and radiated emission. Then the fast algorithm for localized ambiguity function slices is deduced. Finally, Simulation experiments verify the feasibility and validity of the proposed methods.
