Abstract :
The use of bi-/multistatic radar to detect and extract parameters for classification of a hovering helicopter has been studied. An experimental continuous wave bistatic radar has been used in a series of measurements covering a range of bistatic geometries. Variations in detection of rotor tip velocity, number of blades of main and tail rotor and direction of Doppler shift is observed. The use of a series of bistatic receiver pairs (multistatic radar) will increase the ability to extract characteristic parameters that would enhance classification.
