Filed:

Jul 22, 2016

Appl. No.:

15/745382

Inventors:

- San Diego OR, US
Stephen Bennett - Hillsboro OR, US
Keangpo Ricky Ho - Hillsboro OR, US

Ou Yang - Hillsboro OR, US

International Classification:

G01S 13/58
G01S 13/00
B64C 39/02
G08G 5/00

Abstract:

Various techniques are provided to efficiently detect the position and angular velocity of an object relative to a compact radar system including a transmitter antenna array and a receiver antenna array. In one example, a method includes repeatedly scanning a transmitter antenna array and a receiver antenna array of an object sensing system through a plurality of designated transmitter and receiver channels over a period of time to generate a time series of measured channel responses corresponding to each one of the designated channels, determining a time series of directional vectors to or from an object scanned by at least one of the designated channels, and/or a corresponding time series of average phase differences, based, at least in part, on the time series of measured channel responses, and determining an angular velocity of the object from the time series of directional vectors and/or the corresponding time series of average phase differences.

Abstract:

Various techniques are provided to efficiently detect the position and angular velocity of an unmanned aerial vehicle (UAV) of a UAV system including a transmitter antenna array and a receiver antenna array. In one example, a method includes establishing a wireless link between a UAV controller and a UAV using at least one transmitter antenna array and/or at least one receiver antenna array, communicating link state data corresponding to the established wireless link over the established wireless link, generating UAV operational data based, at least in part, on the link state data, wherein the UAV operational data is configured to control operation of the UAV, and controlling operation of the UAV using the UAV operational data.
