de Wit, J.J.M. (author), Harmanny, R.I.A. (author), Prémel Cabic, G. (author)Coherent radar measures micro-Doppler properties of moving objects. The micro-Doppler signature depends on parts of an object moving and rotating in addition to the main body motion (e.g. rotor blades) and is therefore characteristic for the type of object. In this study, the micro-Doppler signature (i.e. the object spectrogram) is exploited to...conference paper 2012
