Do ppler shift lDduced by target rotation bas been widely studied in tbe literature for Its Imaging potential We investigate bere a unique form of target motion reminiscent of tbe precession of a rotating lop. Images are generated with tbe radar looking either along tbe precession axis or or thogonally to It. Features of tbe two methods are discussed and demonstrated by Imaging slmalated point target scenes.

A.bstract-The instrumentation radar described here uses precessional motion of captive targets and a wideband waveform at centimeter wavelengths to derive polarimetric, three-dimensional images. System operation and examples of data from simple shapes and a scaled, real target are discussed.
