Abstract With the rapid development of target detection and tracking technologies, multi-device cooperative detection and tracking operations have imposed increasingly stringent requirements on simulation systems in terms of scale, real-time performance and signal-level fidelity. However, traditional simulation methods struggle to simultaneously meet the demands of multi-device cooperative detection and tracking and closed-loop real-time verification. To address these issues, this paper proposes a design method of real-time simulation system for target detection and tracking devices based on digital-physical integration. This method achieves coordinated operation of digital simulation and hardware-in-the-loop simulation, focusing on solving key technical problems in achieving equivalence between digital simulation and hardware-in-the-loop simulation in terms of real-time performance and signal-level fidelity. Meanwhile, a joint simulation architecture is constructed, comprising multiple digital target detection and tracking devices and one hardware-in-the-loop target detection and tracking device, for testing multi-device cooperative detection and tracking systems and verifying information cooperative interaction. The system comprehensively employs key technologies such as virtual scene generation, relative motion modeling between detection devices and targets, and distributed real-time simulation networks, forming a high-fidelity, scalable simulation environment. Experimental results demonstrate that, under the premise of ensuring real-time closed-loop operation, the system can achieve performance consistency verification between digital target detection and tracking devices and hardware-in-the-loop target detection and tracking devices, effectively reducing testing costs and cycle, and providing a feasible technical approach for engineering development and system verification of multi-device cooperative detection and tracking systems.
