Modern military systems and supporting infrastructure depend upon sensitive semiconductor electronic components to provide their sensing, communications, and weapon system functions. These electronic devices are known to be potentially vulnerable to high-power electromagnetic sources and environments, such as those produced by high-power microwave (HPM), radio frequency, directed energy weapons. HPM is new form of “non-kinetic” energy weapons threats that systems must face in addition to traditional kinetic energy weapons, such as projectiles, rockets, and missiles. HPM weapons can irradiate a target with sufficient energy to couple the energy into the target’s electronics and produce adverse effects that can range from interference to long-term upset to permanent damage, depending upon the HPM weapon’s power and distance between the weapon and target. Several foreign countries are currently interested in this technology and are fielding weapon systems.

The purpose of this webinar is to discuss how to mitigate the effects of HPM weapons and make systems more survivable. First, we will discuss what HPM weapons are and how they can couple energy into a victim system. Next, we will discuss how the HPM energy can affect typical electronics, in terms of temporary electronic upset and permanent damage. We will discuss the different types of HPM weapons and how they are like electronic warfare/electronic attack systems and electromagnetic pulse in some ways but different in others. Next, we will discuss a methodology for estimating the probability of target failure as a function of a weapon’s power density on target and range using DREAM, the Directed Radio Frequency Energy Assessment Model. Finally, we will cover an example of how to estimate the hardening levels for a notional helicopter and some of the technology and techniques that can be used to enhance its survivability against HPM weapons.
