Efficient Estimation of the Helicopter Blade Parameter by Independent Component Analysis

Efficient Estimation of the Helicopter Blade Parameter by Independent Component Analysis

We propose an efficient method to estimate various parameters of a helicopter blade including the number B<sub>num</sub> and the length by separating the blade signal using independent component analysis (ICA) and an analytic solution obtained by monostatic/bistatic geometry. The propose...
