Abstract

Recently, a mutual interference threat has been increasing among the radar systems due to the rapid growth of the military radar operation. In this paper, the radar interference protection criteria is presented for interoperability in terms of the radar coverage and target detection probability in association with the international recommendation on the interference spectrum by ITU-R. The required criteria for the minimum allowable interference is also presented in terms of INR. In order to ensure the maximum detection probability of the radar under the mutual interference situation, only 5 % of detection range loss is allowed for the case of INR of -6 dB, and required SNR is presented at each INR in terms of the detection range and detection probability. This result will be useful for establishing the interference protection criteria in the combined military radar systems.

최근 군용 레이다 사용이 급증하면서 인접 시스템 상호 간의 전자파 간섭의 영향이 높아지고 있다. 본 논문에서는 레이다의 효율적인 운용을 위하여 국제 표준화 규정에 근거하여 군 무기체계 레이다의 탐지거리 및 탐지확률에 미치는 영향을 분석하여 상호운용에 대한 간섭 보호 기준을 제안한다. 레이다 상호 간 간섭이 존재 할 경우에도 요구 탐지거리 및 탐지확률을 확보하기 위한 허용 INR을 제시하였으며, 특히 INR이 -6 dB인 경우 5 %의 탐지거리 손실을 허용하는 조건에서 최대 탐지확률을 확보하기 위한 SNR을 시뮬레이션을 통하여 결과를 제시하였다. 향후 군 통합무기 체계에서 레이다 상호간의 간섭의 영향에 대한 보호기준을 정립하는데 활용될 것으로 기대한다.
