Underwater wideband DOA estimation based on PMC method

A new wideband DOA estimation method based on a time-domain wideband signal model is proposed, which uses population Monte Carlo (PMC) method for the Bayesian calculation. This method needs few snapshots and only requires real arithmetic compared to conventional subspace class method because of use of the time-domain signal model. The PMC method outperforms other MCMC methods due to its parallel processing ability which can reduce the time of the procedure. Computer simulation shows that this method gives a good performance of the DOA estimation.
