An Iterative Method for Direction of Arrival Based on MNLS Solutions
Li Guo · Journal of Chongqing University of Science and Technology · 2009
Traditional subspace direction-of-arrival(DOA) estimation method employs large number of snapshots to calculate the input covariance matrix.Here we introduced an iterative method based on MNLS(minimum norm least square) solution named FOCUSS(focal underdetermined system solver) to estimate DOA.With this method we can get high resolution estimation after a few times iteration,and it employs much fewer receiving snapshots.
