초록

불확실한 측정값 근원의 문제에서는 표적을 최적으로 탐지해내는 것이 유용하다. 본 논문에서는 클러터 환경에서 표적을 추적하는 경우에 탐지확률 및 오경보확률과 동시에 탐지문턱값 처리에 따른 추적오차를 살펴보고, 문턱값과 표적추적 유효화영역의 최적화 알고리즘을 제안한다. 제안한 알고리즘은 시뮬레이션을 통해 상태추정오차공분산의 측면에서 성능을 분석한다.

It is useful to detect the tracking error with an optimal view in the presence of measurement origin uncertainty. In this paper, after the investigation of the targer error dependent on the detection threshold as well as the detection and false alarm probabilities in a clutter environment, a new algorothm that optimizes the threshold of validation region for target trackinf is proposed. The performance of the algorithm is demonstrated through computer simulations.
