Title:
ELECTRONIC DEVICE FOR IDENTIFYING ATTRIBUTE OF OBJECT BY USING MILLIMETER WAVE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/034010
Kind Code:
A1
Abstract:
According to various embodiments, an electronic device using a millimeter wave comprises: a first antenna array; a second antenna array; a communication circuit; and at least one processor, wherein the at least one processor may be configured to: control the communication circuit to output a first signal through the first antenna array; when a first reflected signal acquired from the first signal reflected by an object is received through the second antenna array, determine the range between the object and the electronic device on the basis of the first reflected signal; determine an output period of a second signal on the basis of the determined range; control the communication circuit to output the second signal through the first antenna array according to the determined output period; and when a second reflected signal acquired from the second signal reflected by the object is received through the second antenna array, identify an attribute of the object on the basis of the second reflected signal. Various other embodiments may be possible.
