Modern LADAR sensors have the potential to utilize a number of sensing modalities that provide a rich array of
information in addition to traditional 3D geometry. Imaging polarization, multi-spectral reflectance/absorption
and vibration spectral signature characteristics can all be sensed, potentially in a single LADAR sensor. This
paper will examine how these rich sensing capabilities enhance the utility of LADAR signature exploitation.
This research utilizes a strong understanding of underlying physical phenomena, enabling the development of
data exploitation capabilities that are not brittle to small variations from assumed targets and environmental
conditions, and minimizing the need for experimentally obtained training data. Physics-based signal processing
research has demonstrated a promising ability to extract useful and actionable intelligence from the various
sensing modalities of modern LADAR systems. A summary of the intelligence provided by the LADAR sensing
modalities is presented as well as a demonstration of how the individual modes and combinations of LADAR sensing
modes can be leveraged to add unique and valuable information to intelligence gathering missions. Particular
utility is demonstrated for detection of adversary presence in cluttered, obstructed, hidden or underground environments.
Furthermore, research has shown 3D geometry, polarization, multi-spectral and vibrometry LADAR
sensing modalities can provide valuable intelligence for identifying and/or classifying the adversary and analyzing
