Abstract
A target classification method for radar systems wherein, in particular, jet aircraft, are classified in that the blade repetition rate and, in a further step, the number of blades, of an engine rotor wheel are determined and thus the type of engine is identified. Helicopters are classified by determining the blade repetition period of the primary or tail rotor.
