The traditional PRI transform method has high estimation accuracy for the pulse repetition interval,but its anti-jitter capability is much worse.The modified PRI transform algorithm combines shifting time origins and overlapped PRI bins methods to improve the traditional PRI transform algorithm.Although it has a certain anti-jitter capability after the improvement,it still cannot be obtained in the case of large jitter.In this paper,the least squares method is introduced to segment the jitter signal to reduce the jitter effect,and then combine the traditional PRI transform method to sort the jitter signal.The simulation results show that the signal sorting method has a good effect in the case of large jitter.
