Abstract: Disclosed is a qualitative evaluation method of a volumetric defect density due to other grains having different crystal orientations from a single crystal matrix in a (001) monoclinic gallium oxide sample or a (010) monoclinic gallium oxide sample. The method includes the steps of: forming an etch pit by etching an observation plane of a single crystal; and selecting a quadrilateral etch pit formed by volumetric defects except for void defects.

Abstract: An operating method of a radar sensor includes: performing object classification on a detected target; comparing a confidence score of a result of the object classification with a threshold value; determining whether high-resolution information on the detected target is to be generated based on a result of the comparison; in response to a determination that the high-resolution information is to be generated, selecting one or more of a plurality of analog-to-digital converters (ADCs) of the radar sensor, and determining control information for changing a setting of the selected one or more ADCs; changing the setting of the selected one or more ADCs based on the determined control information; generating first intermediate frequency signals based on respective first reception signals and a frequency modulated signal, the first reception signals being signals received through reception antennas after a first transmission signal output by the radar sensor is reflected by the detected target, and the first transmission signal being generated based on the frequency modulated signal; generating first radar data by processing a portion of the generated first intermediate frequency signals through the selected one or more ADCs; generating second radar data by processing remaining signals among the generated first intermediate frequency signals through remaining ADCs of the plurality of ADCs; generating the high-resolution information on the detected target based on the generated first radar data; and generating high-resolution information on a predetermined range based on the generated second radar data
