System and Methods for Remote Sensing Using Double-Sideband Signals

摘要

A sensing system (100) is provided that includes a transceiver (102). The transceiver includes a transmitter chain that transmits a double-sideband electromagnetic wave having first and second frequency components, and a receiving chain that receives the double-sideband electromagnetic wave after it is reflected by a target. The system (100) further includes a baseband circuit (104) for extracting information content from the double sideband electromagnetic wave. A separation between the first and second frequency components causes a spike in a signal response generated by one sideband of the double-sideband electromagnetic wave to substantially overlap a null point of a signal response generated by the other sideband of the double-sideband electromagnetic wave.
