The objective of this work is the use of the MU radar (49.5 MHz) in Kyoto, Japan, configured as an interferometer, to investigate those processes which appear to cause a "tilting"of refractive index structures. Such tilted layers produce differences in the measured vertical velocity using Doppler techniques. By using the MU radar as both a Doppler device and an interferometer, these thin scattering layers can be observed simultaneously thus producing independent measurements of the entire field of motion.
