Abstract
Airborne meteorological radars and related networks and models. In one embodiment a network for creating a meteorological model includes a mobile sensing node and a modeling node. The sensing node includes a meteorological RADAR that senses the wind velocity. Data from the meteorological RADAR regarding the wind velocity is received by a processor of the modeling node which determines a model of the wind from the wind velocity. The modeling node combines data from a second sampling node with the data from the first sampling node to create a resultant wind velocity vector. Preferably, the modeling node and the sampling node(s) communicate over an airborne WAN. Another embodiment provides a method of measuring the wind velocity. The method includes steering an RADAR signal out of the plane of travel of the mobile platform. The wind velocity is measured using a return of the RADAR signal.
