Abstract:

BACKSCAT is a computer simulation of atmospheric backscatter from a laser radar lidar system. The computer code can simulate operating conditions for a variety of viewing, laser system, and atmospheric conditions. BACKSCAT version 2.0 has been totally redesigned. The redesign effort has included the addition of several new features as well as improvements to the code. As with Version 1.0 BACKSCAT Version 2.0 is modular in fashion. This allows for further expansion and growth in the code. Wind dependent desert aerosols and cirrus clouds have been added. Both are based on formulation used in LOWTRAN 7. The cirrus cloud models include standard cirrus clouds as well as subvisual clouds. An all new User Interface System has also been developed. The new interface is designed to be easy to use while providing the operator with maximum flexibility. The interface system includes a built-in graphics package that permits the user to display the results from a simulation. The interface system also permits the user to include molecular scattering profiles based on a library of built-in model atmospheres or a user-supplied radiosonde profile.
