“…If the value is too small, the calculation time will be longer, and if it is too large, the PRI estimation will be inaccurate, resulting in a larger difference from the true PRI 9 . The CDIF algorithm requires that both the difference value and the two-fold difference value exceed the threshold before sequence retrieval can be carried out, so it is necessary to carry out a large number of calculations to count the multilevel difference histograms, and at the same time, due to the influence of the threshold selection, the false alarm rate of the CDIF algorithm is high, and the PRIs at the subharmonics may exceed the threshold, so that the wrong PRIs are extracted 10 . Compared with the CDIF algorithm, the SDIF algorithm takes into account both the effectiveness of detection and the computational complexity of the algorithm.…”

Radar signal sorting is an important issue in radar electronic warfare, and its accuracy directly affects the identification of radar radiation sources and the effectiveness of electronic reconnaissance systems. This article proposes an efficient radar sorting algorithm. Firstly, the number of pulses in small intervals is counted, and the number of pulses in the interval is calculated. Then, the potential pulse interval is searched for, and the corresponding pulse string of the signal with the potential pulse interval is obtained using an improved sequence retrieval algorithm based on vector dot product. The interference between pulse strings with different PRIs(Pulse Repetition Intervals) is reduced by using the method of successive elimination. Simulation experiments show that the algorithm greatly reduces the calculation time while maintaining high accuracy in radar sorting.
