摘要
Abstract
Since multiple signals classification(MUSIC)algorithm has large calculation quantity and low estimation speed when estimating two⁃dimensional angle of arrival(AOA),two⁃dimensional MUSIC spectrum⁃peak searching algorithm based on data interpolation is studied. On the basis of MUSIC algorithm,larger step is applied to proceed rough searching in two⁃dimen⁃sional space,then two⁃dimensional interpolation is conducted in minizone near searched spectrum⁃peak position. Spectrum⁃peak searching is carried on in the zone with smaller step,and precise angle estimation value is obtained. Simulation experiments in⁃dicate that the algorithm can reduce calculation quantity in two⁃dimensional space searching effectively.关键词
