Line-of-Sight Guidance Control Using Video Images

A mathematical formulation of the line-of-sight control problem is proposed for the case when this line is directed at a target. An operator situated on a moving platform controls the line of sight using the data received from video images. Some functionals determining the quality of control by the operator are introduced. It is proved that, in the case of plane motion of the platform and an infinitely distant target, the problem has a saddle point.
