Deinterleaving of radar signals with stagger PRI and dwell-switch PRI types

Abstract

The main objective of passive Electronic Warfare (EW) systems is to receive radar signals, measure parameters of signals, deinterleave and identify composed clusters of pulses. In a dense environment, identification of each radar signals has had vital importance. Nowadays, EW systems use multi-parameters deinterleaving methods to compose clusters from receiving radar pulses. Then, these clusters are identified by using time of arrival (TOA) deinterleaving methods. In this paper, we will discuss a new deinterleaving algorithm based on predefined parameters for radars which emit stagger and dwell-switch pulse repetition interval (PRI) types. The results of proposed algorithm are simulated via test scenario.
