System for measuring turbulence remotely
First Claim
1. A receiver of electromagnetic energy that travels along a path and is incident on an antenna, the antenna being responsive to incident electromagnetic energy to produce a received signal, the path being subject to turbulence, the receiver comprising:
- an input to accept the received signal;
a circuit in communication with the input, the circuit to accept the received signal and to accept a signal that is representative of a velocity of a mobile platform, at least one of the receiver and a source of the electromagnetic energy being on the mobile platform, the circuit to process the received signal using the velocity signal to remove a shift associated with the received signal because of relative motion between the source and the receiver, the circuit thereby determining an alteration of the electromagnetic energy caused by the turbulence; and
an output in communication with the circuit to output a signal that is representative of the turbulence.

Abstract
A system and method for detecting turbulence includes several mobile platforms, a mobile platform velocity sensor, and several electromagnetic energy transmitters and receivers. The receivers receive the energy transmitted by the transmitter(s) after it has traveled along a path subject to the turbulence. The receivers detect alterations of the energy caused by the turbulence and filter the alterations for effects of the mobile platform velocity (on which either a transmitter or receiver is located). Additionally, the system may create a three-dimensional model of the. In another preferred embodiment, the present invention provides a method of detecting turbulence using a mobile platform. The method includes receiving electromagnetic energy that has traveled along a path subject to the turbulence and determining the alteration to the energy caused by the turbulence. The alterations are filtered of the effects of the velocity of the mobile platform on which the receivers are preferably located.
