System for measuring turbulence remotely
First Claim
1. A mobile platform comprising a receiver configured with at least two antennas to:
- receive a plurality of signals from a plurality of signal sources remote from the platform along a plurality of paths;
condition the received signals to obtain one or more signals representative of clear air turbulence;
condition one of the received signals to obtain a global positioning signal;
determine directions to the signal sources;
use the directions to obtain time varying vectors representing air conditions along the signal paths; and
use the time varying vectors to locate 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.
