Industrial Automatic Control Systems and Controllers Annotation << Back Radar Pointing Determination A.A. Moiseev Base problem of ground-based monitoring is pointing implementation for controlled radar. Some method is developed which based on the directional diagram estimation using sensors matrix exposure. Method optimizes parameters of Laurence or parabolic approximation using least-squares approach. Built equation systems are nonlinear and can’t be solved analytically. In this situation was proposed to use numerical methods for error minimum search. They can be used for approximation maximum position which interpreted as pointing result. Keywords: ground-based monitoring; directional diagram; sensors matrix; Laurence approximation; parabolic approximation; least-squares method; minimum search; numerical methods.
