A criterion for selecting sensor outputs in bearing estimation algorithm without eigendecomposition

고유치분해가 필요없는 방위각 추정 알고리듬에서 센서신호의 선택기준

The performance of the BEWE(Bearing Estimation Without Eigendecomposition) algorithm depends on the sensor outputs which are selected to construct the projection matrix. In this paper, we construct the covariance matrix of the bearing estimates for two targets and propose the criterion to select the sensor outputs which minimize the covariance matrix. The computer simulation conforms that the estimation error is smallest when the sensor outputs are selected based on the proposed criterion.
