Abstract
An antenna arrangement (1) comprising an antenna array is disclosed. The antenna array comprises N antenna elements (2) (N being an integer ≥3). Moreover, each antenna element is connected to an electronics module (3) out of P electronics modules, P being an integer such that 3≤P≤N, where each electronics module is configured to generate an output signal indicative of a signal received by a corresponding one or more antenna elements. The antenna arrangement further comprises control circuitry (10) connected to the antenna array. The control circuitry is configured to receive each output signal, compute a sum of cross-correlations between each output signal and a set of other output signals originating from other corresponding antenna elements, and determine at least one angle of a direction of arrival of the electromagnetic waves relative to the antenna array based on the computed sum.
