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.

Abstract: A process and an apparatus for removal of a lumen filler and/or other soluble residues from hollow filament bundles are described. The hollow filament bundles are first roughly cleaned by centrifuging, after which in a process preferably containing multiple steps they are cleaned by spraying and centrifuging. The first spraying step is preferably carried out in a pass-through mode and each of the additional steps under recirculation. After a constant concentration has been attained, the cleaning baths in each case are employed for a lower-order treatment step, the cleaning bath of the first spraying step being fed to a recycling process.
