Abstract

Abstract:

Considering the complex situations such as unequal data rates, asynchronous tracks, and systematic errors of the co-located radar and electronic support measures（ESM）, an asynchronous anchoring and pairing association algorithm is proposed. Initially, the reference sequence and the time domain processing window are defined, dynamically remove bias and clutter, and weight to generate asynchronous anchor pairing points. Secondly, a parameter interval representation method for co-located radar and ESM under the background of system error is proposed, and a method for solving the phase separation matrix is given. The Jonker-Volgenant algorithm and the classical allocation algorithm are used for correlation determination. Finally, an analysis of the applicability of the algorithm extends to multi-sensor and multi-target scenarios is provided. The proposed algorithm can optimize asynchronous data structures, reduce data redundancy and avoid interference from abnormal data and issues of interval generalization. The simulation results show that the proposed algorithm has a high association accuracy rate in the association of asynchronous non-equal-rate tracks, and has certain stability in complex environments with multi-target and irregular movements.

Key words: co-location, radar, electronic support measures (ESM), asynchronous anchoring and pairing, dissimilarity matrix
