AFSIM Modeling of Base Defense by a Distributed, Synchronized HPM System
High power microwave (HPM) systems are traditionally limited in terms of range. One way to increase the range is to synchronize multiple HPM weapons so that the HPM pulses arrive simultaneously and in-phase. Coherent synchronization of N weapons provides N times the range of a single weapon. General Atomics-Electromagnetic Systems (GA-EMS) has developed a system concept to synchronize multiple, distributed HPM weapons with sub-nanosecond accuracy. This system could be used to synchronize any array of HPM weapons that have sufficiently low firing jitter. GA-EMS has demonstrated this technique in the laboratory and is now developing Advanced Framework for Simulation, Integration, and Modeling (AFSIM) software models to demonstrate its potential effectiveness on the battlefield. These models have been applied to investigate the effect of dividing a single, large, high power HPM system into a distributed array of smaller, less powerful ones. Previously reported simulations showed that multiple, small, unsynchronized HPM systems can be more effective than a single large one at defending a base against an incoming swarm of unmanned aerial vehicles (UAVs). Phase coherent synchronization of the HPM array has now been added to the model, and the simulations demonstrate that synchronization further enhances the effectiveness of a distributed array. The effect of tactics on the performance of synchronized HPM systems, as well as the effect of firing jitter, will be presented.
