Abstract

As the prevalence of broadband coherent sources, a novel algorithm for the direction of arrival (DOA) estimation of coherent signals based on DPT and virtual array is introduced. And one of the algorithms is to be done a comparison, analysis and improvement. It can settle the problem of not finding coherent signals in routine algorithm. This approach can estimate accurately and do not decrease effective array aperture and improve the utilization of array. Simulation results verify the correctness and efficiency of the new algorithm.
