Title:
OBJECT SEE-THROUGH SCANNING DEVICE AND OBJECT SEE-THROUGH SCANNING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/100884
Kind Code:
A1
Abstract:
An object see-through scanning device (100) comprises: a transmission unit (101) that transmits, to a target object (T), transmission radio waves obtained by repeatedly performing frequency sweep which changes a frequency from a first frequency to a second frequency over a frequency sweep time; a reception unit (102) that uses array antenna elements to receive reception radio waves obtained as a result of the transmission radio waves being reflected by the target object (T); a three-dimensional image generation unit (8) that, for each frequency sweep, generates a three-dimensional image from a reception signal from the array antenna elements; and an object detection unit (9) that detects an object on the basis of a plurality of three-dimensional images. At least one of the first frequency, the second frequency, the frequency sweep time, and the number of array antenna elements used in the detection of the object is changed in a time-divided manner.
