Design and Development of an Experimental Platform for Accuracy Assessment of Avionics Fire-Control Systems

In view of the shortcomings of traditional fire control experimental platforms and existing teaching methods in the accuracy evaluation of airborne guided weapons, this paper designs and constructs an experimental platform for avionics fire control systems suitable for guided weapons teaching. The platform adopts a hierarchical and distributed architecture, integrating nine core subsystems covering the whole process from target detection and information calculation to weapon guidance, which restores the typical strike link of guided weapons. It supports full closed-loop simulation through configurable error models. On this basis, centering on the key index of terminal guidance acquisition probability, the study establishes a corresponding accuracy evaluation system, which can conduct sensitivity analysis on the transmission process of various errors in the avionics fire control system, so as to identify and locate the key links and factors affecting the overall fire control accuracy. Verified by practical teaching applications, the platform achieves remarkable effects in cultivating students’ systems engineering thinking and enhancing their practical and innovative abilities. It also provides feasible technical solutions and practical modes for teaching reform and research support in the field of airborne guided weapons.
