Abstract :
The radar backscattering from rotating objects is assumed to be an autoregressive (AR) process of order M. As a practical example reflections from helicopter rotor blades are considered. Within this model the backscattered signals are analyzed by the evaluation of the spectral power density, the pole distribution in the complex plane, and the power cepstrum. Results on simulated and real data are presented and contrasted with conventional processing, i.e. Fourier analysis
