A New Radar Signal Sorting Method Based on Data Field

Abstract

With the increasingly complex electromagnetic environment and continuous appearance of advanced system radars, signals received by radar reconnaissance receivers become even more intensive and complex, because scanning time of radar reconnaissance of each direction is very small, composition of the signals received are very complex, number of signals from different radar emitters differ greatly, traditional radar sorting methods can’t process the signals effectively. Aiming at solving the above problem, a novel radar multi-parameter signal sorting method based on data field and hierarchical clustering is proposed. Data field is introduced to reduce compute capacity and determine the parameters of hierarchical clustering. Hierarchical clustering is known that can obtain multi-level clustering structure of different particle size, by which, we can get small number of radar signals drown in many radar signals. Experimental results show that method presented in this paper can sort radar signals in complex electromagnetic environment effectively.
