Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/029013
Kind Code:
A1
Abstract:
This signal processing device (4) is configured to comprise: a map generation unit (13) that acquires reception signals of reflected waves from a reception unit (1) which receives reflected waves from an object present around a mobile body, and that generates a range-Doppler map indicating signal intensity levels of the reception signals; and an altitude standard deviation calculation unit (15) that calculates a standard deviation of the altitude at which the object is present, on the basis of the range-Doppler map generated by the map generation unit (13). The signal processing device (4) further comprises a collision determination unit (17) that determines, on the basis of the standard deviation calculated by the altitude standard deviation calculation unit (15), whether the object is present at a height at which the mobile body and the object could collide.
