ANALOG BASEBAND CIRCUIT FOR A TERAHERTZ PHASED ARRAY SYSTEM

摘要

A method for determining the position of a target is provided. Several emitted pulses of terahertz radiations are emitted from a phased array (which has several transceivers) in consecutive cycles (typically). These emitted pulses are generally configured to be reflected by a target so as to be received by the phased array within a scan range (which includes a digitization window with several sampling periods). Output signals from each of the transceivers are then combined to generate a combined signal for each cycle. The combined signal in each sampling period within the digitization window for emitted pulses is averaged to generate an averaged signal for each sampling period within the digitization window. These averaged signals are then digitized.
