Abstract :
Micro-Doppler based targets recognition and classification methods are of great significance since it contains more detail characteristics of the targets. A temporal processing method, namely Multi-level delayed and conjugated multiplication (MDCM), is used to compensate macro-motion and realize zooming of the micro-Doppler induced by rotating targets. The performance of the method is demonstrated both by theoretical analysis and computer simulation.
