Abstract

The pulse amplitude of a search radar signal received by an ES system is not constant pulse by pulse because of the radar's scan characteristics. The variation of the pulse amplitude causes the ES detection loss in the ES system. Therefore, the ES detection range equation should consider the ES detection loss caused by the search radar's scan characteristics. In this paper, we theoretically analyze the ES detection loss for the circular scar and propose the model to evaluate it quantitatively. The experiment results for the real search radar signals demonstrate that the proposed model is suitable for the evaluation model of the ES detection loss related to the circular scan of radars.

레이더의 스캔특성에 의해 ES 시스템에 수신된 탐색 레이더 신호의 펄스세기는 펄스마다 일정하지 않다. 이러한 펄스세기의 변화는 ES 탐지손실을 유발하므로 스캔에 따른 탐지손실을 ES 탐지거리 방정식에 고려하여야 한다. 본 논문에서는 원형스캔에 대하여 ES 탐지손실을 이론적으로 분석하고, 정량적으로 예측할 수 있는 모델을 제안하였다. 실제 레이더에 대해 탐지손실을 측정한 결과, 제안된 모델이 원형 스캔에 관계된 ES 탐지손실 모델로 적합함을 알 수 있었다.
