For the purPOse of improving the DOA estimation Performance
we present a newiterative algorithm for estimating the DOA of multiple dappler signals by using both the signal’ Stemporal and spatial structures in the case of less snapshots and low SNR. In this Paper
a simplified algorithm is also presented to reduce the computation. These two algorithms outpefferm theconventional ML method which does not use the signal’ S temporal structure in the case mentionedabove. Monto-Carlo experiments illustrate the efficiency of proposed algorithms.
