英文摘要： The micro-motion characteristics of target have great potentialites in the tasks of radar acquistion and recognition, and get more and more attentions from scientist and engineer community. The main purpose of this project is to extact the micro-motion features from radar returns, including modulating effects induced by micromition, micro-motion features extraction, radar experiments for micro-motion measurement, and so on. There are three parts of innovative products in past 3 year, discovering the multi-component nolinear amplitude and frequency modulation in radar returns induced by target with micro-motions,providing the entire technical resolutions for micro-motion signature acquistion, radar imaging and estimation of micro-motions parameters, pursuiting the radar waveform designation oriented to acquisition of micro-motion characteristic, and conducting the radar experiments to measure the micro-motion characteristic of person and airplane. These research progresses have proposed the worthful ways of obtaining the micro-motion characteristics of radar target not only in signal processing but also in radar measurement, and provided the foundation of state estiamtion and target recognition, as well as some products have been applied in the field of pace surveillance and missile defense. The research team has produced 1 book in Science Press, 4 authorized patents, and more than 20 papers,including 3 in IEEE or IET transations, 5 indexing by SCI.
