ABSTRACT:
A system for detecting turbulence along a path that is subject to turbulence. The system may make use of at least one transmitter to transmit electromagnetic (EM) energy along the path and at least one receiver to receive the EM energy. At least one of the transmitter and the receiver moves along the path. The receiver may have an antenna responsive to incident EM energy to produce a received signal, and an input for accepting a velocity signal indicating a velocity that the receiver or the transmitter is moving. The receiver processes the received signal using the velocity signal to remove a shift associated with the received signal because of relative motion between a source of the EM energy and the receiver or transmitter that is moving along the path. Thus, the receiver determines an alteration of the EM energy caused by the turbulence and outputs a signal indicative of the turbulence.
