In this paper, we present a new high resolution algorithm to localize multiple sources in near-field. After focusing on a pre-estimated location, the covariance matrix of the received signal is found to have the same structure as in the far-field situation, which allows the estimation of bearing with far-field subspace methods. With the estimated bearing, the range estimation of each source is consequently...
Two improvements of the “linear ESPRIT” algorithm in [1] are proposed and applied to the time delay estimation (TDE) from radar data within the microwave range. At first, “linear ESPRIT” is adapted to the TDE. Then, two new linear subspace algorithms, namely ESPRITWED-UG (ESPRIT Without EigenDecomposition) and AV-ESPRITWED (AVerage ESPRIT Without EigenDecomposition) are proposed. Contrary to [1],...
