Abstract
High-resolution algorithms for direction finding of narrowband sources require a good estimate of the noise correlation matrix. We derive a physically motivated linear noise model. It is based on a Fourier expa nsion of the ambient noise field and is applicable to arbitrary antenn a arrays. We also show that for contrived cases, a linear model may no t be uniquely identifiable.
