Abstract

The SPICE (Sparse Iterative Covariance-based Estimation) algorithm estimates the azimuth angle by applying a sparse recovery method to the covariance matrix in the time domain. In this paper, we show how the SPICE algorithm, which was originally formulated in the time domain, can be extended to the frequency domain. Furthermore, we demonstrate, through numerical results, that the performance of the proposed algorithm is superior to that of the conventional frequency domain algorithm.

기존에 제안된 SPICE(Sparse Iterative Covariance-based Estimation) 알고리즘은 시간영역에서 구현되며 공분산 행렬에 sparse recovery 기법을 적용함으로써 표적 방위각을 추정한다. 본 논문은 기존의 시간영역에서 다루던 SPICE 알고리즘을 주파수 영역으로 확장함으로써 주파수 영역에서도 구현 가능함을 보여준다. 또한 기존의 주파수 영역 표적 방위각 추정 알고리즘의 성능에 비하여 제안된 알고리즘의 성능이 우수함을 보여준다.
