【摘要】 压缩传感(compressed sensing或compressive sampling,CS)理论一出现便受到国际上的广泛关注,它打破了经典采样模式,通过随机采样少量点即可精确或以很高的概率恢复原始信号。利用这一特点,提出了一种波达方向(direction of arrival,DOA)估计的新方法,相比于传统DOA估计,只需少量采样点同时达到方向的精确估计,计算机仿真验证了方法的可行性。更多还原

【Abstract】 A new theory known as compressed sensing or compressive sampling(CS)has been presented recent years,which breaks the classical signal sampling rule.According to CS theory,it’s possible to reconstruct sparse or compressible signal from small number of non-traditional samples in form of randomized projections.Taking the advantage of CS theory,this paper introduced a new DOA estimation method,it was realizable to get an accurate DOA estimation at the presence of very few samples compare with the traditional approaches.Experimental simulation provides a proof of the feasibility of this method.更多还原
