Radar-enabled sensor fusion
First Claim
1. A computer-implemented method comprising:
- providing, via a radar-emitting element of a device, a radar field;
receiving, via a radar-receiving element of the device, one or more reflection signals that correspond to a target in the radar field;
transforming the one or more reflection signals to provide radar data;
extracting, from the radar data, a radar feature comprising an indication of a shape of the target;
activating, based on the radar feature, a sensor of the device to provide supplemental sensor data;
augmenting the radar feature with the supplemental sensor data to enhance the radar feature; and
providing the enhanced radar feature to a sensor-based application effective to improve performance of the sensor-based application.

Abstract
This document describes apparatuses and techniques for radar-enabled sensor fusion. In some aspects, a radar field is provided and reflection signals that correspond to a target in the radar field are received. The reflection signals are transformed to provide radar data, from which a radar feature indicating a physical characteristic of the target is extracted. Based on the radar features, a sensor is activated to provide supplemental sensor data associated with the physical characteristic. The radar feature is then augmented with the supplemental sensor data to enhance the radar feature, such as by increasing an accuracy or resolution of the radar feature. By so doing, performance of sensor-based applications, which rely on the enhanced radar features, can be improved.
