Automatic door with radar sensing

A method for controlling an automatic door, comprising:

• capturing millimeter wave (mmW) radar data from a plurality of mmW radar sensors, each of the plurality of mmW radar sensors sensing a different door area;
• registering the mmW radar data to sense a combined door area that includes each door area, wherein the mmW radar data includes a position of a target in the combined door area, the position expressed in three dimensions;
• determining target information about the target in the combined door area based on the registered mmW radar data;
• performing an analysis of the target information;
• and
• controlling the automatic door to open/close based on the analysis of the target information.

A method for controlling an automatic door, comprising:

• capturing millimeter wave (mmW) radar data from a plurality of mmW radar sensors, each of the plurality of mmW radar sensors sensing a different door area;
• registering the mmW radar data to sense a combined door area that includes each door area;
• determining a crossing point of a target based on the registered mmW radar data;
• determining a position of the target based on the registered mmW radar data;
• determining a speed of the target based on the registered mmW radar data;
• and
• ignoring the target if:
• the crossing point is not in a portion of the combined door area designated as a safe zone, the safe zone including a threshold of the automatic door;
• the position is not in the portion of the combined door area designated as the safe zone;
• and
• the speed is not above a threshold speed.

An automatic door system comprising:

• a door control unit (DCU) configured by instructions to:
• receive millimeter wave (mmW) radar data from a plurality of mmW radar sensors, each of the plurality of mmW radar sensors sensing a different door area;
• register the mmW radar data to sense a combined door area that includes each door area;
• determine target information about a target in the combined door area based on the mmW radar data;
• perform an analysis of the target information, wherein the analysis of the target information includes determining at least one of a height, a width, or a shape of the target;
• and
• control a door to open/close based on the analysis of the target information.
