Apparatus and method supporting covert communications using terahertz imaging camera

摘要: An apparatus includes a link receiver having detector array configured to receive radiation from remote communication device, where the multiple detectors. Each horn capture using an antenna positioned in or proximate throat of receiver, is coupled load. also bolometer electrically isolated load and thermal contact with The could include terahertz camera. can be located at focal plane optical system through specified far-field solid angle. transmitter generate transmit second device and/or transmitter/receiver communicate device.
