재밍 환경에서 전자전 수신기를 이용한 다중 표적 추적 기법 연구

Abstract

A tracking algorithm considering the characteristics of threat target tracking in a jamming operating environment is required to interfere and deceive the onboard radars of multiple threat targets(e.g., aircraft and missiles) during the jamming of army communications. This paper proposes a new algorithm for tracking multiple threat targets in a jamming operating environment. The proposed algorithm consists of two stages: 1) tracking of azimuth direction and elevation using an interactive multiple model and a joint probabilistic data association filter; and 2) adaptive adjustment of the noise covariance to solve the untraceable scenario problem for the threat targets. The performance of the proposed tracking algorithm is validated by the results obtained by modeling the simulator considering the threat target characteristics in a jamming operating environment.
