It is well known that monostatic radars are poor meteor-wind radars. It has been suggested, however, that an outboard receiving site, configured as an interferometer, could receive pulses scattered by meteor trails from the STs beams, resolve the geometry, and thus measure winds in the 80 - 110 km region. This approach, dubbed MENTOR Meteor Echoes No Transmitter, Only Receivers, would be an inexpensive way to add mesospheric capabilities to ST radars. The cost of a MENTOR receiver system is expected to be a small fraction of the cost of either a meteor-wind system or an ST radar. In addition, locations such as Colorado and Pennsylvania that have networks of ST radars could use a single MENTOR receiving site to determine winds above all ST radars within a several hundred kilometer radius. This could make possible the measurement of gravity-wave phenomena over much larger horizontal distances that can be accomplished from a single site. A MENTOR workshop was held 21 May 1984. It was concluded that the MENTOR approach in Colorado or anyplace else with a network of MST radars would yield important new information about winds in the mesosphere and about mesospheric gravity waves with horizontal scales of 50-500km.
