Coarse Correction of a High Energy Laser Weapon System with Target Estimation

摘要

Two tracking radars are positioned to determine the position information of a target in their range, which will then be used by two laser guns to track the target. Noise contained in the position information is filtered out using the extended Kalman filter. A radar dynamics model accepts the target dynamics to provide the target position information in terms of azimuthal and elevation angles (w.r.t the radars). From this, the firing angles (i.e. the angles w.r.t the laser guns) are calculated, and are corrected at discrete intervals of time (0.1s). Simulation results of the proposed concepts have demonstrated successful tracking of the target by the laser beams. Also, beam bending phenomena in the atmosphere is conceptualized, and is used to improve the tracking precision.
