The Achievements of Target Characteristic with Micro-Motion

Technical progresses in controlling of target characteristic play the challenge to the tasks of target measurement and recognition. With the development of advanced sensors and time-frequency signal processing, some advancement in target micro-motion measurement and feature analysis gain more and more attentions in the field of target measurement and recognition. In this paper, some topics related to target characteristic with micro-motion are introduced and analyzed, such as the basic concept of micro- motion dynamics, the mechanism of modulation on electromagnetic wave induced by target with micro-motion, progresses in feature analysis of target with micro-motion, and the applied fields based on micro-motion dynamics. Some directions of further work in target characteristic with micro-motion and their technical difficulties are predicted at last.
