An Improved Algorithm of PRI Transform

It is a difficult problem to deinterleave radar radiating source in the electronic countermeasure field at present, the pulse repetition interval (PRI) constant and PRI jitter pulse sequence can be deinterleaved by PRI transform algorithm, but it has some disadvantages. The deinterleaving right rate is affected by the range of PRI value, and the PRI transform algorithm is not useful to PRI stagger pulse sequence. In order to resolve the two problems, an improved algorithm is proposed in this paper, and simulation results show that this improved algorithm is effective.
