Damage Assessment Simulation of Shipborne High-Energy Laser Weapon

Different from traditional naval gun, high-energy laser weapon firing laser to an aim point on the target for several seconds to achieve target damage. In fact, It's a process of energy accumulated. To destroy air target, process of laser pointing is analyzed, including calculation of elevation angle, azimuth angle of laser beam and killing time in ideal situation. Considering heave movement of navy vessel and the spacing between sensor and laser weapon, laser pointing model is established in stable coordinate system of vessel, by adopting method of coordinate transform and coordinate conversion under the influence of swaying navy vessel. Calculating accumulated energy, threshold energy, killing time and average facula area, damage assessment simulation model is established on the basic of laser pointing model. Requirements of error precisions are proposed by simulation results.
