In real-world environments, the numerous testing equipment and battlefield conditions present limitations such as high execution difficulty and high costs, making it difficult to conduct large-scale, high-frequency live-fire tests.

[0003] Patent CN202210181986.1, "Method and System for Multi-Service Joint Training and Evaluation," discloses a training and evaluation method for anti-ship missiles and surface vessels used in the Navy and across different services. This method utilizes satellite communication to establish cross-regional communication among multiple services. It employs real-time missile flight simulation technology and real-time evaluation of missile firing effects in simulated combat scenarios within a realistic context. While this method can be extended to other equipment systems, it requires a scenario where multiple platforms can be online in real-time to complete joint training and evaluation. Since conducting operational evaluations of avionics systems in realistic scenarios is costly, there is an urgent need for a comprehensive verification and evaluation system based on a hardware-in-the-loop simulation platform.
