Abstract

Sideband Doppler modulation caused by micro motion of targets on radar echoes is called micro-Doppler effect. Vibration, swing, rotation, coning, precession and nutation are the most common kinds of micro motion. In this paper, micro-Doppler is induced by coning motion mathematically. Then echoes of point scatterers are modelled with linear frequency modulation (LFM) signal. This paper mainly studies the performance of micro-Doppler extracted from echoes of targets with translation compensated completely under different bandwidth. It is more beneficial to extract micro-Doppler characteristics of each scatterer respectively as the bandwidth grows wider, when different scatterers can be separated in range profile domain. At last, the analysis of performance is verified by simulation.
