The PEGEM overview provides a high-level multimedia introduction to
PEGEM purpose and functionality, including movies, and simulation
environment examples.

Instructions are also provided on this website that indicate how government agencies and government contractors may obtain a free copy of the PEGEM software.
The Post-Engagement Ground Effects Model (PEGEM) is a lethality
system toolkit principally centered on chemical, biological,
radiological, nuclear, or conventional high explosive (CBRNE)
weapons/agents and missile defense.
PEGEM is a powerful simulation tool that seamlessly integrates complex ground effects modeling elements, yet is easy to use and operate.
|
|
|
|
Written in C++, PEGEM operates on PC (2000/XP) platforms.
PEGEM integrates a suite of models to produce a
comprehensive simulation incorporating all phases of ground effects
assessment and consequence management:
-
Unitary Chemical Source Term Modeling
-
Munition and Solid Debris Propagation
-
Radiological Dispersion Device Source Term Modeling
-
Atmospheric Transport and Dispersion
-
Casualty Modeling
-
Meteorological Effects – (Temporal and spatially
variable)
-
Unit Effectiveness (AURA Interface)
-
Force-on-Force Model Interface
-
Currently DIS (Distributed Simulation Capability)
and HLA (High Level Architecture) Compliant
-
CADRG, DRG, ADRG & VPF maps
-
LANDSCAN & P95 Population Models
-
LANDSCAN Terrain Type Data
-
DTED Terrain Elevation Data
-

Below
are several examples of the PEGEM simulation environment. You
may click on a thumbnail image to view the image in a larger

Simulation setup is quick
and easy, using a variety of pull-down menus to select
geographical areas and other features. Using stored
National Imaging and Mapping Association (NIMA)
vector product format (VPF) data, the user may
choose to model geographical features, such as land
contour or infrastructure. The image of Europe to the
left incorporates an infrastructure overlay showing
major roads and airports |

Population density is represented by the circles in this image.
The footprint from a Unitary Chemical Warhead is depicted, with
Lethal Dosage estimates based on government toxicity standards
mapped to various colors. Lethality is interpreted by the key in the
lower left corner (example: LD95 signifies that a 95% mortality rate
will occur in the area in pink).

Shown here
is a footprint with multiple plumes inside a populated area defined by
LandScan data, typical of Magnus Rotor Bomblet Submunitions with biological
agent. |
| |
|
|
Multiple events may be processed and reviewed. Sample events are shown overlaid
on an ADRG map
|
|
 |
|
|
|
|
 |
|
Events can be processed with
spatially and temporally varying weather/terrain conditions. In this
example, the plumes are displayed with translucency to show the underlying
terrain.
|
|
|
|
|
Through a menu option, the user can switch between
the traditional 2D map display and a 3D texture-mapped Earth. Users
orient the 3D Earth scene using the mouse allowing them to view event
information such as the trajectories, centroids, and ground hazards.
This capability permits expanded viewing capabilities displaying threat/submunition/debris animation and more robust ways
of displaying longer range threats/trajectories.

Beginning with version 6.0,
PEGEM wll be capable of dealing with selected nuclear weapon effects, in
addition to the radiological dispersion device capabilities already in
place. In version 6.0, PEGEM will deal with fallout, including reporting
various dose and dose rate types and calculating personnel casualties. The
next future version of PEGEM will address the classic prompt effects:
nuclear radiation, blast and thermal. |
