Description: A number of laser propagation codes have been assessed as to their suitability for modeling      Army High Energy Laser (HEL) weapons used in an anti- sensor mode. We identify a      number of areas in which systems analysis HEL codes are deficient. Most notably, available      HEL scaling law codes model the laser aperture as circular, possibly with a fixed (e.g. 10%)      obscuration. However, most HELs have rectangular apertures with up to 30% obscuration.      We present a beam-quality/aperture shape scaling relation which can be useful when      applying these codes to realistic designs for HELs.
