Apparatus and techniques for 3d reconstruction with coordinated beam scan using millimeter wave radar

Abstract

Certain embodiments are directed to techniques (e.g., a device, a method, a memory or non-transitory computer readable medium storing code or instructions executable by one or more processors) for object detection and three-dimensional reconstruction of objects using coordinated beam scanning. The disclosed techniques teach coordinated beam scanning that can be used for both detecting proximity to personnel in addition to detecting objects for three-dimensional object reconstructions. The techniques form one or more millimeter wave beam that can be electronically steered by adjusting the phase of the various antenna elements. The techniques can include saving the plurality of grid points for which the object is detected to a memory for detecting a range to the object for Maximum Permitted Exposure (MPE) limit monitoring and three-dimensional object reconstruction.
