Abstract
A device includes a processor, a radar sensor with a transmitter, a first receiver, and a second receiver. The device operates the sensor in a first operational mode that utilizes the transmitter and the first receiver, but not the second receiver. The device detects, using the sensor in the first operational mode, possible motion of an object within a threshold distance from the sensor. Responsive to detecting possible motion of the object, the device transitions the sensor from the first to a second operational mode that utilizes the transmitter and the first and second receivers. The device transmits, while using the sensor in the first operational mode, a first number of radar frames in a first time interval and transmits, while using the sensor in the second operational mode, a second number of radar frames in the first time interval, the second number being greater than the first number.
