Title:
RADAR DEVICE, PRESENCE DETERMINATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/005830
Kind Code:
A1
Abstract:
This radar device comprises a surface area calculation unit (30) for calculating a surface area by integrating reflection power and a presence determination unit (30) for determining whether an object is present within a predetermined close range from a transmission and reception unit. The presence determination unit (30) determines that an object is present within the close range if the following first condition is met: the current surface area calculated by the surface area calculation unit (30) for a specific range is larger than a reference surface area that was calculated for the specific range by the surface area calculation unit (30) when no object was present in the close range.
