Abstract: Water tank experiment system for wideband array high resolution DOA(Directional Of Arrival) estimation is constructed. A number of wideband ML(Maximum Likelihood) DOA estimator based on MCMC(Markov Chain Monte Carlo) technique are tested by the experiment systems. Experimental results show the algorithm can accurate estimate azimuth of targets whose intersection angle small than half of beam-width.
