Abstract:

The dynamic quality of maneuvering target tracking fire control integrated system is analyzed. Firstly, an algorithm for maneuvering target tracking is suggested, which has higher accuracy of tracking. Secondly, under the assumption of multi time scales separation, by use of the technique of forced singular perturbations, sub optimal control strategies are expressed in a feedback form expressing explicitly the dependence on the measurable target state variables and aircraft performance parameters. Based on the algorithm and strategies above, a tracking fire control integrated system is proposed, which is in accordance with actual combat. Finally, an imaginary air defense scenario is simulated. The system analysis shows that the integrated system has longer lock time, and the burden of numerical calculation is remarkably reduced.
