Abstract :
Micro-Doppler signatures can be regarded as a unique signature of an object with movements and provide additional information for classification, recognition and identification of the object. In this paper, we concentrate on radar micro-Doppler signature extraction from high speed targets with micro-motions. Compensation of range migration brought by high speed, translation Doppler shift adjustment, radar signal requirement, and micro-Doppler signature extraction method are discussed. A kind of micro-Doppler analysis method for high speed targets is simulated and the simulation results validate it.
