Abstract

This paper describes an improved location determination scheme based on the triangulation method calculating a target position. The proposed scheme uses coordinates of intersection points of three circles each generated by measurement of an observer. The target position obtained from the proposed scheme has higher accuracy not only at the vicinity, but also at the periphery of the observation area. The maximum error and the average error with the proposed scheme are reduced by 40.89% and 40.30%, respectively, with respect to conventional methods.

본 논문에서는 목표의 위치를 결정하기 위해 사용되는 삼각법을 개선한 위치추정 방법을 제안한다. 제안하는 방법은 세 원간의 교점들을 통해 목표의 위치를 추정한다. 이 방법을 통해 결정된 목표의 위치는 기존의 방법과 같이 관측지역 중심에서 높은 정밀도를 갖고 기존의 방법에서 큰 오차를 갖는 관측지점 주변에서도 높은 정밀도를 갖는다. 이 방법은 기존의 방법보다 최대오차에서 40.89%, 평균오차에서 40.30%가 줄었다.
