Abstract A few issues of studying micro- and macro-motions by a Doppler radar are reviewed. Ability to simplify multicomponent radar signals is explored. A new model of a rotating scatterer is suggested for forming a dictionary of functions. The model takes to account some particular issues associated with the micro-motions. It is assumed to approximate real micro-Doppler signals for increasing performance of recognition systems based on micro-Doppler radars. New features can be extracted due to the model representation. The main aspects of using the signal representation for moving object detection and recognition are considered.
