Abstract:

The modulation signal for the rotating helicopter blade is derived in Reference 1. Two basic models were proposed in this reference a model based on scattering from the blade tip and a specular flash model. Evidence presented in Reference 2 is somewhat inconclusive, although the statement is made that most of the echo is derived from the outer portions of the rotor blade approximately the outer 20 of the blade length. Such a statement supports the model where scattering is assumed to occur at the blade tip. Author
