Abstract

The Toeplitz approximation method (TAM) of stochastic system identification is applied to the linear equally-spaced-array narrowband source direction-finding problem. The proposed algorithm provides high-resolution direction-finding and is designed for an arbitrary-noise, multipath signal environment. As such, it extends existing capability in fields such as passive sonar, radar and communications. A simulation comparing TAM and the MUSIC method, using spatial smoothing, is presented for low signal-to-noise-ratio (SNR) data and a multipath environment.
