Abstract
In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device comprises an antenna array, a wireless communication module electrically connected to the antenna array and configured to form directional beams through the antenna array, at least one processor operatively connected to the wireless communication module; and a memory operatively connected to the at least one processor. The memory stores instructions causing the at least one processor to perform a plurality of operations comprising: transmitting a sequence of first directional beams having a first beam width to scan first regions having a first size through the antenna array, receiving a sequence of first reflected waves generated by reflection of the sequence of the first directional beams from an object through the antenna array, transmitting a sequence of second directional beams having a second beam width narrower than the first beam width to scan second regions, which are included in the first regions and have a second size smaller than the first size, through the antenna array based on at least a portion of the received sequence of the first reflected waves, receiving a sequ…
