Abstract

Due to underestimation of rough surface scattering at retro-reflection direction, consideration of enhanced backscattering (i.e. opposition effect) can be critically important in developing laser radar signatures. This is illustrated by the comparison of two signature models of the same airplane--one developed using bidirectional reflectance measurement data at one degree from the retro-direction, and the other developed from monostatic measurement data at true retro-direction. The unique instrument used to obtain the laser reflectance data, the reflectance data itself, and the software ensemble used to develop the signature are described and discussed.
