Abstract:
In the complicated radar signal environment, sorting the radar signal pulse correctly is essential to provide efficient data for radar pulse modulation feature recognition and direction finding and localization. A sequence searching method based on pulse repetition interval (PRI) transform algorithm is proposed. The most possible PRI of the target radar is got with the PRI transform under the high pulse losing probability. With the proposed method, the pulse of the PRI is extracted from the pulse flow. By double threshold searching, this method minimizes the possibility of sorting the false pulse due to the high pulse density and the large threshold value. Finally, the simulation of the method is made to sort the target radar including staggered radar, jittered radar and frequency agility radar pulse effectively.
