Abstract: An object velocity detection method includes: obtaining a first reception signal and a second reception signal that are received in different time intervals through a radar sensor; determining a Doppler effect based on the first reception signal and the second reception signal; determining an angle value of an object based on a signal obtained by compensating for the Doppler effect; obtaining a compensated signal by compensating for the angle value in the second reception signal; and determining a velocity of the object based on the compensated signal.

Abstract: An object detection method and apparatus are provided, the object detection method includes receiving a radar reception signal reflected by an object using a radar apparatus, generating a data set for one or more reflection points of the object by processing the radar reception signal, and detecting the object corresponding to the reflection points based on the data set using a neural network-based object detection model.
