Abstract
Provided is a method and device for recognizing a pointing location by using a radar. A device according to an embodiment of the present disclosure comprises: a weight value space generation unit for generating a weight value space comprising a plurality of unit spaces in a space in front of the screen, and setting weight values in proportion to intensity of clutter-removed reception signals of the plurality of radars to the unit spaces; a hand area detection unit for adding up the set weight values for each of the unit spaces of the weight value space; an effective radar selection unit for selecting, as an effective radar, a radar having a shortest distance to the detected hand area among the plurality of radars; and a finger position determination unit for detecting a first location (first path) exceeding a predetermined threshold value.
