Radar-based system for sensing touch and in-the-air interactions

A method comprising:

• at an electronic device that includes one or more radar-based transmitters and one or more radar-based receivers;
• transmitting, from one or more of the radar-based transmitters, radio waves into an area in a vicinity of the electronic device;
• receiving, at one or more of the radar-based receivers, radio waves reflected off one or more objects in the vicinity of the electronic device;
• and
• processing the radio waves as reflected off the one or more objects using a radar imaging module.

A system, comprising:

• one or more radar-based transmitters;
• one or more radar-based receivers;
• one or more processors;
• and
• a non-transitory memory coupled to the one or more processors and comprising instructions executable by the one or more processors, wherein the one or more processors are operable in response to executing the instructions to initiate operations comprising:
• transmitting, from the one or more radar-based transmitters, radio waves into an area in a vicinity of an electronic device;
• receiving, at the one or more radar-based receivers, radio waves reflected off one or more objects in the vicinity of the electronic device;
• and
• processing the radio waves as reflected off the one or more objects using a radar imaging module.

A system, comprising:

• a first plurality of radar-based transceivers;
• a second plurality of radar-based transceivers;
• wherein each radar-based transceiver includes a radar-based transmitter and a radar-based receiver;
• wherein the first plurality of radar-based transceivers is configured to transmit first radio waves into a first area in a vicinity of an electronic device and receive the first radio waves reflected off of one or more first objects in the first area;
• wherein the second plurality of radar-based transceivers is configured to transmit second radio waves into a second area in the vicinity of the electronic device and receive the second radio waves reflected off of one or more second objects in the second area;
• and
• one or more processors configured to process at least one of the first radio waves as reflected or the second radio waves as reflected in response to determining one or more stored application requirements corresponding to user gestures to be detected.
