A ladar system and related method are disclosed where the ladar system comprises first and second receivers. The first receiver receives a ladar return from a ladar pulse with a known transmit polarization. The second receiver receives the ladar return from the ladar pulse with the known transmit polarization. The ladar system also includes a control circuit that (1) measures incident polarizations at the first and second receivers with respect to the received ladar return and (2) separates a retro-reflective portion of the received ladar return from a non-retro-reflective portion of the received ladar return based on the measured incident polarization and the known transmit polarization.
