Short-Range Micro-Motion Sensing with Radar Technology — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

This Chapter gives an Introduction to the broad design phases of radar motion sensing. Due to the technical advancements in semiconductor, signal processing, and system integration, radar has emerged as a promising technique for short-range motion sensing, detecting an object's relative displacement motions with very high accuracy. It can be used as a solution for noncontact gesture sensing as it transmits radio frequency signals to the target, and the target's movement can be extracted by analyzing the backscattering reflections. It is a promising and attractive form of HCI for emerging applications in wearable, mobile, and ubiquitous computing, where the traditional touch interaction is not desired or difficult if not impossible.
