LIDAR-PC
Ontar's LIDAR-PC
models pulsed laser radar and lidar systems
(hard target and atmospheric aerosol backscatter
applications). Input parameters include,
among others, laser power per pulse, target
reflectivity, and telescope diameter. For
any arbitrary slant path, LIDAR-PC calculates
the return signal as a function of range.
The user can input atmospheric attenuation
and backscatter coefficients or to use the
weather conditions specified in the BETASPEC
module. This module is a user-friendly version
of the US Air Force's BACKSCAT (version
4.0) program. High resolution molecular
attenuation (transmission) is obtained from
HITRAN.
The output is a data array of the backscatter
and aerosol attenuation coefficients as
a function of wavelength and altitude. The
BETASPEC output file contains the attenuation
and backscatter coefficients of aerosols
(clouds, dust, etc.). The HITRAN output
file contains the attenuation coefficients
of molecular gases (CO2, CH4,
H2O, etc.)
