This paper describes a method to classify targets especially helicopter by evaluating their vibration signa-tures. The mechanical vibrations of the targets are mainly caused by all moving parts ( engines, turbines, gears, etc. ). Different types of targets have different vibration spectra. These were measured in the field by an experimental heterodyne laser radar. The measured signals show type characteristic vibration signatures. These can be evaluated by proper mathematic algorithms so that classification of noncooperative targets is possible.
