Dr. Donald W. Hoock,
Jr. - Effective training entails simulations of possibilities encountered
during combat. It is essential to be able to identify and prepare for
possible equipment disruptions. Such disruptions can happen due to natural
or man-made causes.
The Soviet Army in central Europe planned to use smoke
and obscurant munitions that would blind the U.S. Army’s sensors and prevent
long-range standoff capability. While working with the U.S. Army Research
Laboratory at White Sands Missile Range, Dr. Donald W. Hoock, Jr. helped
coauthor a computer program that helped deter the Soviet Army’s smoke
For several years, a model Hoock coauthored was the
lead project of the U.S. Army Atmospheric Sciences Laboratory’s Atmospheric
Effects division. The Combined Obscuration Model for Battlefield-Induced
Contaminants model was coauthored by Hoock in 1983. COMBIC predicted the
effects of dust, smoke, and obscurants on U.S. Army target acquisition and
surveillance systems. It was adopted by the Army war gaming community and
remains today the primary model used in Army war gaming simulations to model
obscurant smoke, dust, and haze effects. It provides modelers with
“predictions of temporally varying visibility and transmission loss
information for dozens of specific types of modeled battlefield obscurants.”
Hoock’s work did not stop with COMBIC. Although the
model provided general information about the cloud position, other important
concepts were not well understood. The evolution of obscurant clouds, the
behaviors of obscurant clouds in a complex terrain, such as urban
environments, and the way light traveled through spatially variable smoke
plumes were poorly understood.
A year after the completion of COMBIC, Hoock began
working on an extensive research program to gain a better understanding of
obscurant clouds. Between 1985 and 2004 he led a major research effort
involving 11 coauthors and publishing over 32 papers and reports covering
these research areas.
The research resulted in the “development of a
breakthrough cloud visualization algorithm, termed STATBIC, the Statistical
Texturing Application to Battlefield-Induced Clouds. The model helped
understand the unpredictable characteristics of real battlefield clouds,
like those with non-repeating variations in shape and concentration that may
have holes. These unpredictable characteristics “produce significant
performance variations in target acquisition, tracking, designation, weapon
homing, and design aspects for low observables of electromagnetic systems
propagating or detecting radiation through or near them.”
Hoock was awarded the Department of the Army Research
and Development Achievement Award for his work on “High Resolution Radiative
Transfer Visualization of Smoke and Dust Clouds” in 1992.
He retired from the U.S. Army Research Laboratory at
WSMR in 2012. He passed away in 2012.
