Passive imaging with multistatic polarimetric radar

In this work we present a study applying polarimetric principles to passive radar imaging. We assume a stationary scene illuminated by spatially distributed transmitters with unknown location and polarization. The scattered waves are captured by spatially distributed stationary receivers equipped with a pair of orthogonally polarized antennas. We model the target as a set of dipoles. Using this model, we derive a set of templates for spatially resolved detection. Our aim is to show that one can recover valuable information about the target through polarimetric consideration in a passive detection setting that exhibits both polarization and spatial diversity.
