Abstract
This paper present a parametric method that yields an estimate of directional-of-arrivals of multiple broad-band wavefronts impinging on a synthetic antenna. The method use the Maximum Likelihood Estimator applied on broad-band signals. The antenna is a synthetic one formed by a moving hydrophone. To improve the bearing estimation, we use a sliding spatial window along the antenna. We present a comparison with the MUSIC method on the basis of experimental underwater acoustic data.
