PRI-based radar signal binning algorithm and simulation implementation

In a radar signal sorting system, sorting based on PRI features is an important part of the system, and PRI classification is generally divided into two parts, one is to determine the PRI value, and the other is to perform sequence retrieval based on PRI. This paper first describes the PRI characteristics of several typical radar signals, and then introduces in detail several classical PRI feature extraction algorithms, such as the dynamic extended correlation algorithm, the statistical histogram algorithm and the CDIF algorithm, and carries out theoretical analysis and experimental validation of these algorithms.
