Abstract

ES (Electronic Warfare Support System) collects radar signals, and analyzes the signals about frequency, pulse width, PRI (Pulse Repetition Interval), and etc. and then ES compares analyzed result with known radar signals to identify them. But there are two disadvantage. One is that use of known radar signals is in comparing step only. The other is that calculating PRI needs many operations. In this paper proposes a parallel reference correlation algorithm that uses GPGPU (General Purpose Graphics Processing Units) and can identify what signals are in received radar signals without calculating PRI.

전자전지원 시스템(Electronic Warfare Support System)은 레이더 신호의 식별을 위해 수집한 신호의 주파수, 펄스폭, 펄스반복주기(PRI, Pulse Repetition Interval)등의 정보를 분석한 후 기존의 알려진 레이더 정보와 비교한다. 기존의 연구는 두 가지 단점이 있다. 첫 번째 단점은 기존의 알려진 레이더 정보를 마지막 비교단계에서만 비교한다는 점이다. 두 번째 단점은 PRI를 계산하기 위해 많은 연산이 필요하다는 점이다. 본 논문에서는 사전에 알려진 레이더 정보를 초기단계에서 활용하여 PRI를 계산하지 않고 수집된 신호에 미리 알고 있는 레이더 신호의 존재 여부를 식별하는 방법을 제안한다.
