On the Improvement of Bearing Estimation Algorithm Using Automatic Tracking Window

자동 추적 윈도우를 이용한 방위각 추정 알고리즘에 개선에 관하여

This paper proposed a preprocessing algorithm which is named Automatic Tracking Window (ATW), which eliminates the effects of noises at spatial signals and spurious peaks at high-resolution algorithm in bearing estimation algorithm. This method estimates spatial spectrum by periodogram algorisdthm and hihg-resolution algorithm after preprocessing of spatial signal by automatically tracked window.
