End-to-end modeling with the HEIMDALL code to scope high-power microwave systems

In this paper, we describe the expert-system code HEIMDALL, which is used to model full high-power microwave systems using over 60 systems-engineering models, developed in the course of over a decade, that describe the prime and pulsed power, microwave sources, antennas, platforms, and propagation. We show an example of our calculations of the mass of a Supersystem producing 500-MW, 15-ns output pulses in the X band for bursts of 1 s, interspersed with 10-s interburst periods.
