This is intended to be the second year of a previous two-year continuing grant (PI: Robert Palmer, Institution: Clemson University); the grant has been transferred to the University of Nebraska. 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.

今年是前一笔为期两年的持续赠款的第二年(PI：Robert Palmer，机构：克莱姆森大学)；赠款已转移到内布拉斯加州大学。这项工作的目的是使用日本京都的MU雷达(49.5 MHz)，配置为干涉仪，调查那些似乎导致折射率结构“倾斜”的过程。这种倾斜的地层产生了利用多普勒技术测得的垂直速度的差异。通过将MU雷达用作多普勒设备和干涉仪，可以同时观测到这些薄散射层，从而产生对整个运动场的独立测量。
