1. An automatic door system comprising:
a door assembly including an automatic door;
a plurality of millimeter wave (mmW) radar sensors, each mmW radar sensor configured to capture mmW radar data; and
a door control unit (DCU) that is communicatively coupled to the plurality of mmW radar sensors and the door assembly, the DCU configured by software instructions to:
determine target information about a target based on combined mmW radar data from the plurality of mmW radar sensors;
process the target information to classify the target, the target classified as a nuisance when the target information includes a height that is below a threshold, the threshold depending on an open/close state of the automatic door;
filter the target from controlling the automatic door when the target is classified as the nuisance;
process the target information to estimate one or more parameters for door control; and
control the automatic door to open or close based on the one or more parameters for door control.
