Abstract
We present an efficient algorithm for high resolution time delay estimation in colored Gaussian noise with multiple looks. By using a relaxation-based optimization approach and exploiting the Toeplitz property of the noise co variance matrix, the enhanced new algorithm can achieve the corresponding C ramer-Rao bounds (CRBs) with a very small number of independent looks.
