Abstract
In an embodiment, a millimeter-wave system includes a first circuit having M channels, one or more antennas coupled to the first circuit, and a controller that includes a resource scheduler module. The controller is configured to operate the millimeter-wave system as a radar device and as a communication device based on an output of the resource scheduler module.
Claims26
A millimeter-wave system comprising:
- a first circuit having M channels, wherein M is a positive integer greater than 1;
- one or more antennas coupled to the first circuit;
- and
- a controller comprising a resource scheduler module, the controller configured to operate the millimeter-wave system as a radar device and as a communication device based on an output of the resource scheduler module, wherein the one or more antennas comprise M/2 antennas, wherein each pair of channels of the M channels of the first circuit is coupled to a respective antenna of the M/2 antennas, wherein each pair of channels comprises a first channel that corresponds to a vertical polarization of the respective antenna and a second channel that corresponds to a horizontal polarization of the respective antenna, and wherein the controller is configured to operate the first channel of one pair of channels for radar operations of the radar device, and the second channel of the one pair of channels for communication operations of the communication device.
