Abstract
A system for suppressing noise by frequency dither includes a transmitter, receiver and a frequency dither circuit, as well as a cavity along a propagation path of the electromagnetic signal between the transmitter and the receiver. The transmitter is configured to transmit an electromagnetic signal to the receiver at each of one or more selectable frequencies. The frequency dither circuit is configured to apply a frequency dither to the electromagnetic signal transmitted from the transmitter to the receiver at each of the selectable frequencies. In this regard, the applied frequency dither has a span having been selected as a function of a minimum frequency period of an expected standing wave in the system, and a rate having been selected as a function of a signal processing bandwidth for sampling a frequency spectrum including the selectable frequencies.
