Title:
RADAR IMAGING DEVICE, RADAR IMAGING METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/218965
Kind Code:
A1
Abstract:
This radar imaging device, upon acquiring a radar signal by controlling an antenna that receives a reflected wave of an electromagnetic wave emitted to a target space P, generates, on the basis of the radar signal, a two-dimensional image showing the state of a prescribed height region S that is located at a prescribed height in the target space P and extends in two-dimensional directions. Next, the radar imaging device detects a target object region T that includes a prescribed target object from within the two-dimensional image. Additionally, this radar imaging device (10) generates, on the basis of the radar signal, a three-dimensional image that shows the state of a portion (image-forming space U) which is a partial space in the target space P and through which the target region T passes when the target region T is moved in the height direction of the target space P.
