Radar system transmitter beamforming using occupancy map data

A system, comprising:

• at least one transmitter unit and at least one receiver unit;
• and
• a controller, configured to:
• determine an occupancy map, wherein the occupancy map identifies a location and a probability value associated with the location,
• determine, using the occupancy map, a beamforming weight vector, wherein the beamforming weight vector is configured to enable a determination of a gain of a radar signal, wherein the gain is at least partially determined by the probability value associated with the location in the occupancy map, by optimizing the beamforming weight vector so that radar signals transmitted to the location have a first gain when the probability value has a first probability value and a second gain when the probability value has a second probability value, wherein the first gain is greater than the second gain when the first probability value indicates higher uncertainty than the second probability value, and
• transmit, using the at least one transmitter unit, the radar signal using the beamforming weight vector.

A method, comprising:

• determining an occupancy map, wherein the occupancy map identifies a location of an object with respect to a radar system and a probability value associated with the object;
• determining, using the occupancy map, a beamforming weight vector, wherein the beamforming weight vector is configured to enable a determination of a gain of a radar signal, wherein the gain is at least partially determined by the probability value associated with the location in the occupancy map, by optimizing the beamforming weight vector so that radar signals transmitted to the location have a first gain when the probability value has a first probability value and a second gain when the probability value has a second probability value, wherein the first gain is greater than the second gain when the first probability value indicates higher uncertainty than the second probability value;
• and
• transmitting, using at least one transmitter unit of the radar system, a radar signal using the beamforming weight vector, wherein a gain of the radar signal is at least partially determined by the probability value.
