초록

본 논문에서는 RF탐색기 측정치인 산란점 모델링 기법에 대해 제안한다. 우선 상대자세 각 따라 변화하는 ISAR 영상(Inverse Synthetic Aperture Radar Image)로부터 기준 산란점을 생성하였다. 다음으로 RF탐색기 측정치의 주요 불확실성 요소인 잡음세기(noise strength), 깜박임(blink), boresight 오차를 기준 산란점에 부가한다. 본 연구에서 제안된 RF탐색기 모델은 다양한 표적추적 필터 알고리듬 개발에 사용할 수 있다.

In this paper, we suggest a measurement modeling of the RF seeker using the ISAR(Inverse Synthetic Aperture Radar) image. Reference scattering points are extracted first from ISAR images which are changed according to target attitude. And then uncertainties included in RF seeker measurement such as noise strength, blink, and boresight error are added to the reference scattering points. The proposed measurement model of the RF seeker can be used to develop various kinds of target tracking algorithms.
