Background
• RAFAEL is developing an airborne radio for
Here's
the Israeli Air Force
where
we
• A digital simulation is used to evaluate the
come in compliance
system's performance - including
with operational specs
• Operational scenarios are required as input
for the simulation

Profile
• Speed & altitude
• Special profiles:
– Bomb Run
– CAP
– etc.

Topography
Affects Communication
Problematic to Model
• LOS obstruction by terrain
• Sensitive to Geography
• Very large variance
• Signal attenuation due to
refraction, diffraction,
reflection & interference
Suggested Approach
• Terrain attenuation modeled as
stochastic variable
• LOS elevation above "flat terrain" is
parameter of probability distribution

Methodological Conclusion
• A Scenario is a Model of Reality
tension between Accuracy & Simplicity
• It is a Benchmark for system performance
should be demanding but plausible
• It involves Uncertainty
requires use of stochastic terms
• It is defined in two languages
– military-operational (Airforce-ish)
– engineering language (Software-ish)
