Abstract :
This paper addresses the problem of DOA estimation using the weighted subspace fitting (WSF) scheme in the presence of array manifold error. A modified WSF algorithm using the quasi-Newton method is presented with some computer simulations, and a concise derivation of the formula for the first gradient is given
