There are not too many antennas in the VHF range in the world dedicated to radio astronomy. ST, and specially MST, radars require and have large antenna apertures which could also be used for radio astronomical observations. Definitely, the Jicamarca antenna, the largest in the world (300 m x 300 m), ...

Data from the mesosphere-stratosphere-troposphere (MST) radar at Jicamarca, Peru, together with other available data, are used to diagnose the mean structure of winds and gravity-wave momentum fluxes from the surface to 90 km during two ten-day campaigns in June and August of 1987. In the stratosphere ...

Fine structures E region field-aligned irregularities were observed on June 24–25, 1989, with the MU radar at Shigaraki, Japan (34.9N, 136.1E; geomagnetic latitude 25.0N). The 3.2-m scale irregularities were observed with the MU radar in five main beam directions, each of which was nearly perpendicular ...

It is now known that turbulence and mixing in the lower stratosphere occurs in intermittent layers of thickness between about 30 and 300 meters. Layered structures also exist in the ocean (Woods, 1969) and in the atmospheres of the other planets (Gierasch and Conrath, 1987). It appears that dissipative ...

The high-power VHF radar technique is a powerful tool to lnvestigate winds and turbulence in the middle atmosphere. However, an entire wind or power profile from the upper troposphere to the lower thermosphere. (10-100 km) has not yet been obtained.- Especially, it is very difficult to observe the ...
