DOA estimation using a relaxation based method
Adil S. Jahan · 2000
A modified relaxation based method is employed to minimise the maximum likelihood function in the estimation of the DOA of signals impinging on an antenna array. The method is suitable for estimating DOAs of coherent signals and in the case where the number of snapshots is limited. Simulation results are used to demonstrate the performance of the relaxation-based method relative to that of other methods. (7 References).
