Summary:A family of conditionally Gaussian signal models for synthetic
aperture radar (SAR) imagery is presented, extending a related class of
models developed for high resolution radar range profiles. This signal
model is robust with respect to the variations of the complex-valued
radar signals due to the coherent combination of returns from scatterers
as those scatterers move through relative distances on the order of a
wavelength of the transmitted signal (target speckle). The target type
and the relative orientations of the sensor, target, and ground plane
parameterize the conditionally Gaussian model. Based upon this model,
algorithms to jointly estimate both the target type and pose are
developed. Performance results for both target pose estimation and
target recognition are presented for publicly released data from the
MSTAR program
