In order to implement the individual recognition of Phased Array Radar (PAR) emittersan analysis is made to the formation of the antenna pattern of PARand a PAR emitter recognition method is proposed based on the array antenna pattern.The method calculates the heading angle of the antenna array by using the data from two ESMsand obtains the function of the array factor.By comparing the received antenna pattern with the array factor functionthe antenna element pattern of the array is obtained.By matching the calculated element pattern with the element pattern in databasethe recognition of individual PAR emitter is implemented. The method extracts the inherent characteristics of the antenna pattern of the PAR to recognize the identity of the PAR emitter.The experiments demonstrate that the method is effective.
