Abstract

Based on a newly proposed nested array, we consider the problem of direction of arrival estimation for wideband sources. This array provides O(N²) degrees of freedom with O(N) sensors, enabling us to estimate K sources with N<K sensors. To employ the nested array for wideband source estimation, we propose a novel strategy to apply nested-array processing to each frequency component, and combine all the spectral information of various frequencies to conduct estimation. Similar to the narrowband case, the nested array achieves great performance for wideband scenarios. Numerical simulations demonstrate the advantage of our strategy.
