This document describes techniques and devices for radar-based object detection for vehicles. A radar-based object detection component implemented in a vehicle is configured to detect characteristics of persons within the vehicle, such as a driver or other passengers. Based on the detected characteristics, an activity of the person can be determined and various operations can be initiated based on the activity, such as initiating a warning when the driver is not paying attention to driving or automatically slowing down the vehicle. In some cases, the radar-based object detection component can also be implemented to detect characteristics of objects positioned external to the vehicle, such as pedestrians, other vehicles, or objects in the road. The radar-based object detection component may also be implemented to authenticate a driver of the vehicle, such as by detecting biometric characteristics of the driver or recognizing a series of gestures corresponding to an authentication sequence.
