Abstract

In electronic support systems, the analysis of PRI modulation characteristics for radar signals has attracted much interest because of the problem of the identification ambiguity in dense electronic warfare signal environments. A new method of recognizing the PRI modulation types of radar pulse signals is proposed for electronic support. The proposed method recognizes the PRI modulation types using the classifiers which are based on the property of the linear autocorrelation of the PRI sequences for each PRI modulation type. In addition, the proposed method estimates the PRI modulation period for the PRI modulation types with the periodicity. Simulation results are presented to show the performance of the proposed method.

ES 시스템에서 레이더 신호의 PRI 변조특성 분석은 고밀도 전자전 신호 환경에서의 레이더 식별 모호성 문제로 인해 그 중요성이 증가되고 있다. 본 논문에서는 ES를 위한 레이더 펄스 신호의 PRI 변조형태를 인식하는 새로운 기법을 제안한다. 제안한 기법은 PRI 시퀀스의 선형 자기상관관계에 나타나는 각 변조형태별 특징을 기반으로 정의한 형태 구분자들을 이용하여 PRI 변조형태를 인식한다. 또한 제안된 기법은 주기적인 변조특성을 갖는 PRI 변조형태에 대해서 변조주기를 추정한다. 제안한 기법의 성능을 입증하기 위해 다양한 모의신호에 대한 실험결과를 제시하였다.
