Directions of Arrival Estimation Based on Improved Particle Filter

The directions of arrival(DOA)parameter estimation based on particle filter are discussed and studied.A new method available to estimate DOA parameter based the unscented particle filter(UPF)is presented.The simulations show that both method based PF and UPF are effective for DOA estimation.But the unscented particle filter(UPF)method for DOA estimation is better than the particle filter method in reli- ability and real time processing.
