Abstract
In this paper, the Toeplitz Approximation Method (TAM) of stochastic system identification is applied to the linear equal spaced array narrowband source direction finding problem. The proposed algorithm provides high resolution direction finding capability and is designed for an arbitrary noise, multipath signal environment. As such, it extend existing capability in fields such as passive sonar, radar and communications. A comparitive simulation between TAM and the MUSIC method, using spatial smoothing, is presented which are based on low signal-noise-ratio (SNR) data and a multipath environment.Keywords
