System and method for processing multi-directional frequency modulated continuous wave wireless backscattered signals

Abstract

In an example, the present invention provides an FMCW sensor apparatus. 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 FMCW signal and covert the incoming FMCW signal into a base band signal, and a plurality of transmitting antenna. Each antenna array has a transmitter integrated circuit coupled to the transmitting antenna to transmit an outgoing FMCW signal. The apparatus has a virtual antenna array configured from the plurality of receiving antenna and the plurality of transmitting antenna to form a larger spatial region using the virtual antenna array, than a physical spatial region of the plurality of receiving antenna.
