Automatic door with radar sensing

An automatic door can include a plurality of millimeter wave (mmW) sensors that are each configured to sense a door area. Each mmW sensor includes a mmW radar configured to capture mmW radar data and an inertial measurement unit (IMU) configured to measure an orientation of the mmW radar. Based on I...

Beschreibung
Zusammenfassung:	An automatic door can include a plurality of millimeter wave (mmW) sensors that are each configured to sense a door area. Each mmW sensor includes a mmW radar configured to capture mmW radar data and an inertial measurement unit (IMU) configured to measure an orientation of the mmW radar. Based on IMU data from the mmW sensors, the mmW radar data from the sensors can be combined so that the door areas can form a combined door area. Multiple targets can be detected and tracked through the combined door area at high resolutions and in a variety of environmental conditions. Control of the automatic door can be enhanced in a variety of ways by classifying the targets and predicting their movements in the combined door area. Further, the classification and prediction of targets can facilitate safe and reliable operation by filtering operation based on certain targets and/or motions.
