Abstract
Aspects of the disclosure relate to radar-based signaling for detecting, measuring, and/or characterizing a target object. An electronic device may transmit a plurality of detection signals and receive a plurality of reflection signals reflected from the target object. The electronic device then processes the plurality of reflection signals to extract one or more parameters of the target object. Based on the reflection signals, the device can measure and/or characterize the target object, e.g., to obtain a heart rate and/or breathing rate. In other examples, the device may determine whether the reflection signals indicate human vital signs, such as a heart rate or breathing. The electronic device may then adjust at least one transmission parameter based on whether human vital signs are detected at the target object, and transmit the adjusted signal using the transmission parameter. Other aspects, embodiments, and features are also claimed and described.
