HEL atmospheric propagation library, intersection mesh library, and HEL demos.

Atmospheric propagation library

Currently the atmospheric data must be “included” in the WSF input stream in order to
utilize the HEL models. One does this by inserting the following line into one’s input file:

include_once $(MY_PATH)%/coefficients.txt,

where MY_PATH is the path to the location of the coefficients.txt file, for example:

define_path_variable MY_PATH c:swdevwsf_uhel_demoatmosphere.

For detailed information about supported atmosphere models and wavelengths,
see either the ./atmosphere/AAA_README.txt file or the WSF documentation command entry for “fluence_model.”

Intersection Mesh Library

Currently the only two intersection meshes defined are for a RED_ADV_FIGHTER_2, and
short range air to air IR missile. These are to be included on target platforms, using the intersection
processor (see WSF documentation). It is hoped that more meshes will be added to this library
in the future.

Note: If one cannot use an intersection mesh and intersection processor, intersections
will be computed generically, either as a head-on incidence, or using the incidence
angle to compute a cosine roll off.

ground_hel_vs_hypersonic.txt

Megawatt-class ground-based HEL engages and destroys a hypersonic vehicle passing overhead.
This demo includes a scripted time delay, meant to simulate the HEL’s locking onto the target

intersect_mesh_test.txt

BLUE_MULTIROLE_FIGHTER_1EF W/HEL engages an air target (red_adv_fighter_2) A HEL-equipped blue player chases a red
player, intending to shoot the IRST (region on the red_adv_fighter_2 intersection mesh).
The script continually checks the target to see if the IRST is occluded.
Initially it is occluded. so there is no shot until the red player maneuvers
and the IRST becomes visible.

intersect_mesh_test_beam_director.txt

This is a nearly identical test case with the above. The difference is that we are
using a WSF_BEAM_DIRECTOR and WSF_CUED_LASER_WEAPON instead of the WSF_LASER_WEAPON of
the more simple example above. Intersection mesh tests are done transparently by the
beam director model.

hel_demo.txt

This demo is still in development. It is meant to set up static test cases for
each viable HEL mission.
