摘要 建立了宽带阵列高分辨方位估计水池实验系统,进行了宽带最大似然方位估计快速算法的水池实验研究。研究结果表明,基于马尔可夫链蒙特卡罗方法宽带最大似然方位估计快速算法分辨能力强,突破了二分之一波束宽度,估计出了目标的方位。 Water tank experiment system for wideband array high resolution DOA(Directional Of Arrival)estima-tion 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.
