【Abstract】 Ideas of this dissertation are generated from the engineering practice of the fire control system. This dissertation deals mainly with the optimization problem of information transmission between the subsystems of fire control system. Based on the criterion of smooth and timeliness of information transmission, different solutions are given for information transmission between the subsystems. Theories and technologies stated in this dissertation are to support the demonstration, design and test of rapid-shot anti-aircraft gun fire control system in fields of short range air defense and antimissile theoretically and methodologically. It is an applied theory research project in this field.Firstly, for the optimization of information transmission between two-coordinate target indicating and the three-coordinate target tracking equipment, based on the assumption of linear motion of target, and based on the two-dimension coordinate information (azimuth, distance) of the acquisition radar, the estimation method of the target height and distribution area is given. Multi-filter operation which based on initial value of multi target heights narrows down vertical search range of target tracking equipment and provides such a strategy that target tracking equipment could capture target faster and enter the state of target tracking as soon as possible.Secondly, for the optimization of information transmission between laser measurement and video tracking system, aiming at the missed measure problem of laser range finder, given that the tracking errors of the laser range finder is white noise, the probability distribution rale of the laser range finder’s continuous missed measure time is given. Regarding the probability of maximum allowable continuous missed measure time of the laser range finder as an index, the satisfied solving method of PI controller parameter regions of the laser range finder tracking system is give. Thus, it gives out controlling strategy of fire control computing and the continuity of gun tracking and firing.Thirdly, for the optimization technology of man-machine information transmission in the tracking system, namely, the man-machine cooperation problem in fire control tracking subsystems, the operator satisfactory modeling method is given. By bringing exceeding tolerance indexes into operator satisfactory modeling, a simplified method of identifying parameters of operator model is proposed. This method is based on exceeding tolerance indexes (the average exceeding tolerance rate, the average exceeding tolerance frequency) and stable error coefficient index. Regarding to discrete and continuous system, operator modeling (parameters) sets that satisfy expected index set above are explained by graphics, respectively. Lastly, for the optimization of information transmission between target tracking system and gun driving system, and to ensure the first hit point can locate at the boundary of maximum hitting range, an analytic extension method on the approximation function of firing tables is put forward, which lead to the maximization of the effective hitting range of the gun. And also this analytic extension method gives a smooth turning strategy for the gun at the point of maximum effective hitting range.更多还原
