Beschreibung
Zusammenfassung:	A covered enclosure surface sensing device, with an on-chip 2-D phased array radar sensor, beam-steering to create a three-dimensional image of the enclosure's interior. An environmental encasing contains a processor, a motion detector, a communication module coupled to an external communication antenna, a power source. It is attachable to a lid or upper side surface of the enclosure. After scanning, the device measures positions of, if present, flexible surfaces and obstructions within the enclosure and a level of liquid or powder in the bottom of the enclosure. If the enclosure contains an open channeled inlet and outlet, it measures liquid levels in the inlet and outlet, the position of the inlet and outlet, and the speed of fluid in the inlet and outlet. If the motion detector detects a threshold movement of the lid or surface sensing device, the phased array radar sensor performs a reorientation scan.
