Abstract:

EPETITIVE MOTIONS. The interpretation of the spectral edge loses its accuracy, as one might expect, from the power spectra of moving but nonperiodic nor repetitive objects. Although the point scatterers are used in motions with higher degrees of freedom, it is sufficient to point out that for any real object, the power spectrum can be quite complex and perhaps unique if the periodic motion is stable relative to the radar line-of-sight over a long observation time. The implication is that one might be able to characterize a spinning object through long observation of its power spectrum but the lack of an accurate interpretation of the spectral edge precludes any identification effort without a priori information of the geometry of the object.
