Abstract

Radar signal analysis of electronic warfare is a technique for identifying a radar type by signal parameters(direction, radion frequency, pulse repetition interval, pulse width, scan period..) extracted from a received radar pulse. However as the modern radar and new threat environments is advanced, radar identification ambiguity arises in the process of identifying the types of radars. In this paper, we analyze the problems of the existing method and propose a new method. This technique determines the validity of the scan period by the difference in the arrival time of the radar pulse and the minimum number of scan period discrimination. Experiments proved that the scan cycle results are derived regardless of the RMS((Root Mean Square) of the input amplitude.

전자전에서 레이더 신호 해석은 수신한 레이더 신호에서 추출한 신호제원(방향, 주파수, 펄스반복주기, 펄스 폭, 스캔주기)으로 레이더 종류를 식별하는 기술이다. 그러나 신형 레이더, 위협환경이 고도화되면서 레이더 종류를 식별하는 과정에서 레이더 식별 모호성(Ambiguity)가 발생한다. 본 논문에서는 기존 방법의 문제점을 분석하고 새로운 방법을 제안한다. 이 기술은 레이더 스캔 주기의 펄스 도착시간 차이와 스캔주기 판별 최소 수집 개수로 스캔주기 유효성을 판별한다. 실험에 의하여 입력된 신호세기의 RMS((Root Mean Square)와 무관하게 스캔 주기 결과를 도출하는 것을 입증했다.
