| Summary: | 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 proposed method is composed of two parts, one for even B<sub>num</sub> and one for odd B<sub>num</sub>. For even B<sub>num</sub> the blade parameters are estimated using ICA plus analytic estimation. For odd B<sub>num</sub> the parameters are estimated using two ICAs plus analytic estimation. Experimental results using the radar signal of a blade model calculated by physical optics demonstrate that the proposed method successfully separates the blade signals for both even and odd B<sub>num</sub>s and estimates parameters with high accuracy. |
