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