Abstract

In this paper, we propose a new method to quickly deinterleave the stagger PRI signals and D&S(Dwell and Switch) PRI signals from the EP radar using the electronic warfare system. While former algorithms were based on stochastic methods only using the first deviation of the TOA of radar signals, this paper uses the first and the second deviation of the TOA of radar signals to deinterleave multiple PRIs of EP radars. When we simulate multiple PRIs of EP radars and test the simulated radar signals using the proposed algorithm, various PRI signals such as fixed, jitter, D&S and stagger PRI are well deinterleaved in a short time. This algorithm is found to be very useful for electronic warfare systems.

본 논문에서는 전자전시스템을 사용하여 전자보호(EP) 레이더에서 송신되는 D&S PRI(pulse repetition interval) 신호와 스태거(stagger) PRI 신호를 신속하게 분석하는 새로운 방법을 제안하였다. 기존의 PRI 신호분석 방법은 레이더 펄스신호들의 도착시간(TOA)의 1차 차분을 이용하여 통계적인 방법으로 PRI 패턴을 분석하였으나 본 논문에서는 펄스신호들의 TOA 1차 차분과 2차 차분을 이용하여 다양한 PRI 패턴을 빠른 시간에 분석할 수 있는 방법을 제안하였다. 다양한 EP 레이더 PRI 신호들을 모의해서 송신한 후에 본 논문에서 제안한 알고리즘으로 신호식별을 수행한 결과 고정 PRI, 지터 PRI, D&S PRI, 스태거 PRI 등 다양한 PRI 신호들에 대한 식별능력이 우수하여 EP 레이더의 신호식별에 매우 유용하게 사용할 수 있을 것으로 판단된다.
