Modeling and Error Analysis for Airborne Fire Control System

The relations among operational aircraft, measuring unit for target parameters, airborne weapons and fire control system are described by means of mathematical and physical concepts and methods in the paper. With the constraint conditions that weapons must hit targets, the relation expressions between conception model and control model vs. pointing error and design error have been established. The purpose of the airborne fire control system is to improve hit accuracy for target and reduce shooting error as far as possible. The task for improving the hit accuracy against targets can be well finished through system recognition, structural parameters recognition and numerical simulation.
