Radar using personal phone, tablet, pc for display and interaction

A radar system comprising:

• a transmit array comprising a plurality of transmit antenna elements;
• radar transmitter electronics in signal communication with the transmit array, wherein the radar transmitter electronics, in conjunction with the transmit array, are configured to output a frequency modulation continuous wave (FMCW) transmit beam that illuminates an area with a greater extent in a first illumination direction than in a second illumination direction, wherein the second illumination direction is substantially perpendicular to the first illumination direction;
• a receive array comprising a plurality of receive antenna elements;
• and
• radar receiver electronics operable to:
• receive a plurality of receive signals from the receive array;
• and
• processing circuitry operable to:
• digitally form a receive beam from the plurality of receive signals;
• determine one or more characteristics of a sub-area of the area illuminated by the FMCW transmit beam, wherein the sub-area is within the receive beam;
• establish a communication session with an external display device;
• and
• output a signal to an external display device, wherein the signal comprises:
• target detection information in three dimensions, the three dimensions including range, azimuth and elevation;
• and
• target movement characteristics, including relative velocity and angular velocity.
