Abstract

This paper describes a method for classifying targets -- especially helicopters -- by evaluating their vibration signatures. The mechanical vibrations of the targets are mainly caused by all movements of engines, turbines, gears, etc. Different types of targets have different vibration spectra which were measured in field trials by an experimental coherent laser radar. The measured signals show the type characteristic vibration signatures. The signatures can be evaluated by mathematic algorithms. Therefore classification of noncooperative targets is feasible.
