Abstract
Techniques and apparatuses are described that enable digital beamforming for radar sensing using a wireless communication chipset. A controller initializes or causes the wireless communication chipset to use multiple receiver chains to receive a radar signal that is reflected by a target. A digital beamformer obtains baseband data from the wireless communication chipset and generates a spatial response, which may be used to determine an angular position of the target. The controller can further select which antennas are used for receiving the radar signal. In this way, the controller can further optimize the wireless communication chipset for digital beamforming. By utilizing these techniques, the wireless communication chipset can be used for wireless communication or radar sensing.
