Abstract

The Electronic Support System collects and analyzes the received radar signals in order to cope with the electronic attack in real-time. The radar-pulse clustering system classifies the radar signals that are considered to be emitted by a single source. This paper proposed a radar-pulse clustering algorithm based on four kinds of features: the direction, frequency, pulse width, and the difference of arrival time between two successive pulses. The experiment results show that the proposing algorithm could trace the moving emitter and classify the timely separated signals into different classes.

전자전지원시스템은 실시간 전자 공격에 대처하기 위해 레이더 신호를 수집하고 분석한다. 레이더 펄스 클러스터링 시스템은 단일 소스에 방사되는 것으로 예상되는 레이더 신호를 분류한다. 본 논문에서는 도착방향, 주파수, 펄스 폭, 연속된 펄스의 도착시간의 차이 4가지 특징을 기반으로 한 클러스터링 알고리즘을 제안하였고 실험을 통하여 제안한 알고리즘이 이동방사체의 추적과 시간적으로 분리된 신호를 다른 군집으로 분리함을 보였다.
