From page 19...
... The VESTA technology is based on the fact that physical motions of target objects wall cause slight modulations of the reflected signals for example, the sound vibrations of a mown" vehicle modulate the return signal when the vehicle is illuminated by radar. Based on the modulated return, empirical, non-pattern-matching algorithms can be used to identify the class of vehicle and even to recognize a particular vehicle's unique vibrational pattern, provided the algorithm was previously "trained" on that vehicle's signal.
