In the development of modern guided weapons and advanced sensing systems, the seeker plays a pivotal role as the core component for perception and guidance. Its dynamic performance directly determines the operational effectiveness and reliability of the overall system. To ensure that seekers can maintain accuracy and stability under highly dynamic and complex environments, this solution introduces a comprehensive Composite Seeker Dynamic Performance Test Platform, designed to provide full-scale testing, validation, and optimization of seeker performance.

The system is built upon an HRT hardware-in-the-loop (HIL) simulation verification platform, enabling precise control and joint tuning of both three-axis and five-axis motion simulators. This allows for accurate simulation of the seeker’s dynamic response across diverse spatial attitudes. By supporting both open-loop and closed-loop testing modes, the system not only evaluates the seeker’s intrinsic sensing and response characteristics but also simulates realistic flight conditions with integrated target kinematics and missile dynamics models. This dual-mode structure ensures test results are both comprehensive and reliable.

Functionally, the solution delivers high-speed digital control, high-frequency data acquisition, and real-time visualization, achieving real-time simulation requirements at a 1ms step size. IO hardware boards are supported for direct signal acquisition from seekers, enabling precise recording and subsequent comparative analysis against simulation models. Moreover, the system maintains open compatibility with third-party data processing software, empowering users to extend capabilities within their existing development ecosystems.

The platform supports full control of seeker power-on and power-off states and can simulate missile flight postures under both static and dynamic conditions, providing robust testing of seeker stability and accuracy under high dynamic stress. It further enables the modeling of seeker-related digital dynamics, operational state switching, and IO hardware models, creating a full-stack simulation environment spanning from hardware to software layers. All collected data can be processed and displayed in real time, greatly enhancing visibility and efficiency throughout the testing workflow.

Thanks to its high precision, real-time capability, and strong system compatibility, this solution is ideally suited for open-loop interface testing as well as closed-loop real-time simulation validation. It is particularly valuable in the development of next-generation multi-mode seekers for applications involving high-maneuver target interception, operation in complex electromagnetic environments, and advanced seeker fusion technologies. By applying this solution, developers can rapidly determine key performance parameters, optimize seeker design, accelerate the R&D process, and significantly enhance overall seeker performance.

The Composite Seeker Dynamic Performance Test Solution represents a critical technological platform for the future of seeker research, validation, and optimization, delivering essential support for the advancement of high-end defense and aerospace systems.
