Abstract

Success in modern war depends on electronic warfare. Therefore, It is very important to identify the kind of Radar PRI modulations in a lot of Radar electromagnetic waves. In this paper, I propose an algorithm to identify Linear up Sliding PRI, Non-Linear up Sliding PRI and Linear Down Sliding PRI, Non-Linear Down Sliding PRI among many Radar pulses. We applied not only the TDOA(Time Difference Of Arrival) concept of Radar pulse signals incoming to antennas but also a rising and falling curve characteristics of those PRI's. After making a program by such algorithm, we input each 40 data to those PRI's identification programs and as a result, those programs fully processed the data in according to expectations. In the future, those programs can be applied to the ESM, ELINT system.

현대전에서의 전자전은 전쟁에 있어서 승패를 좌우한다. 따라서 적의 미상 레이더에서 방사하는 전자파를 수신하여 신호 처리 후 레이더의 변조방식을 식별하는 일은 전자전에서 중요한 핵심 과제이다. 본 논문에서는 최근 전자전 보호능력이 우수한 Linear Up Sliding PRI, Non-Linear Up Sliding PRI 방식과 Linear Down Sliding PRI, Non-Linear Down Sliding PRI 방식을 자동 식별하는 알고리즘을 TDOA(Time Difference Of Arrival) 개념을 적용하여 개발하였다. 안테나로 입력되는 레이더 펄스마다 각 제원을 산출하고 제원 중에서 펄스반복간격의 PRI값으로부터 시간차의 특성을 산출하여 식별 알고리즘을 개발하였다. 알고리즘을 프로그래밍한 후 표본 PRI데이터 를 입력하여 처리한 결과, 모두 정확히 PRI변조방식을 식별하였다. 개발된 알고리즘은 향후 ES(ESM, ELINT)장비에 적용 가능할 것으로 판단한다.
