mmWave Water vs. Ground Classification Lab

This lab demonstrates the usage of TI mmWave sensors to differentiate between water and ground. The fundamental principle being demonstrated is the ability of TI’s mmWave sensors to detect extremely fine movement of the target using phase measurement. Ripples in water introduce measurable phase difference in the reflected signal which can be used to classify water from a solid surface (e.g. ground). The lab provides full source code and a CCS project and runs on the TI mmWave sensor xWR14xx EVM.
