The problem of the optimal position configuration of shipborne UAV graranteeing laser teminal guidance projectile in shooting at various kinds of targets on the shore is stuided.Based on the analysis of reflection characteristic of targets on shore,a model of received power was established for laser teminal guidance projectile.Combining with the features of field of seeker,the dispersion characteristics of the initial point to control projectile and the length of time in scanning and searching,the capture model of the projectiles seeker was established.Based on the overall consideration of functions and safety of shipborne UAV in process of fight,the space configuration of shipborne UAV was established and optimized,which provides a decision-making basis for formation commander.
