Abstract Sorting of radar emitters is a vital technology of the radar countermeasure system. To solve the problem that the traditional methods which are based on the Pulse Repetition Interval (PRI) can not sort the signal of PRI complex modulated effectively, this paper introduces a new method which use two-dimensional feature vector that consists of Time Of Arrived (TOA) with frame period to sort radar signals of PRI complex modulated. Even in noisy environment it can get appropriate accuracy of sorting. Extensive Monte Carlo simulation results indicate the effectiveness of the method.
