Abstract
In an example, the present invention provides an UWB and FMCW sensor apparatus, with an audio module and inertial motion module. The apparatus has at least three transceiver modules. Each of the transceiver modules has an antenna array to be configured to sense a back scatter of electromagnetic energy from spatial location of a zero degree location in relation to a mid point of the device through a 360 degrees range where each antenna array is configured to sense a 120 degree range. In an example, each of the antenna array has a support member, a plurality of receiving antenna, a receiver integrated circuit coupled to the receiving antenna and configured to receive an incoming rf signal and covert the incoming rf signal into a base band signal, and a plurality of transmitting antenna.
