Synthetic aperture radar image signatures of rotating objects

This work develops the theory of image signatures of rotating objects in synthetic aperture radar images. The mathematical results are similar in form to the expressions describing vibrating objects. The differences lie mainly in the fact that the expansion parameters in the phase for rotating objects are typically too large to be expanded to first order, as is done in the micro-Doppler vibrational image analysis. These results have potential application in target recognition systems, as rotating components of larger targets cause specific types of identifiable image aberrations.
