Full polarimetric turntable target signature data is used to develop Inverse Synthetic Aperture Radar (ISAR) plots to analyze high resolution target scatter centers. The data was collected using in-scene calibration reflectors to correct for transmit and receive polarization distortions in amplitude and phase. Scatter centers identified to have high radar cross section (RCS) with strong persistency are then analyzed in full polarimetric scatter matrix (PSM) space to discover uniqueness between target types. Target decomposition techniques are used to analyze the target centers. A unique scheme for isolating the effects of a desired scatter phenomenology is described in this paper with results shown for a truck target.
