Atmospheric Characterization of the Marine Base Layer for a Submarine Based High Energy Laser
MetadataShow full item record
Building upon our past research into directed energy weapons and atmospheric propagation of high-energy laser (HEL) beams, we have analyzed the performance of a notional 30 kW to 50 kW HEL weapon with emission from a submarine platform. This analysis modeled the laser from its source on the submarineﾒs mast to targets at various ranges and elevations. We estimated the performance of the laser in a wide variety of configurations, mast heights, weather conditions, and engagement geometries using the ANCHOR code developed by the NPS Physics Department. Since a submarine-based laser would be fired from a beam director located up to 15 feet from the ocean surface, characterization of the turbulence near the surface is critical. To do so, we used NAVSLaM, a turbulence model developed by the NPS Meteorology Department that has been experimentally validated near the surface, and then incorporated the output of NAVSLaM into ANCHOR.
