1. In a method for estimating the multi-path delays in a signal received at an antenna array of k antenna elements, comprising estimating an impulse response at each k antenna, generating a space-time impulse response, forming a covariance matrix and resolving the covariance matrix with a known antenna array manifold, the improvement comprising the step of resolving the covariance matrix with a fictitious antenna array manifold.
