Optical Tracking System "line Of Sight And Independence," Engineering Design And Implementation

Optoelectronic tracking gimbal is fixed on the turret of self-propelled antiaircraft artillery, it can rotate around it's level axis and vertical axis freely. When the turret rotates around it's the gimbal is brought passively, and the line of sight is disturbed. This trouble is solved by the line of sight stabilization specially.The line of sight stabilization is the special and it is one of the important function of the optoelectronic tracking system which applied in self-propelled antiaircraft artillery, and will produce very profound influence to the function of the whole weapon system. Relied on actual work, how to design and realize is the focus in the paper.1.Realization of the line of sight stabilization, the difference both the line of sight of the antiaircraft artillery's fire control system typed P56 of Italy and own are given. What related the line of sight stabilization is analyzed in the first part of the paper, which is the premise of line of sight stabilization, Such as the definition and transform of reference frame. The principle of the line of sight stabilization of the antiaircraft artillery's fire control system typed P56 of Italy was analyzed, and the difference between P56's line of sight and what the author wanted.2.Three kinds of operation mode was elaborated, including semi-automatic mode, guide mode, automatic tracking mode.3.The system depended on the scheme in this paper was tested through experiments on the test equipment. And some troubles revealed in the test were solved.4.There is guiding significance in engineering by above analyses and experiment results.
