System Diagnosis Framework for Sustaining the Operational Fidelity of a Radar System

The ability of a system to operate within its acceptable range under various operating conditions is essential in determining its reliability. In this paper, a health management framework is developed for the continuous assessment and confidence in the operational fidelity of a given radar system. The complexity of such a system makes it challenging to implement a comprehensive prognostics and health management approach effectively. For this reason, the system is analyzed at the subsystem level to consider components' degeneration within each subsystem. In the proposed framework, sensors are used to collect relevant data from critical components for system diagnosis. Subsequent preprocessing and analysis can then be used in developing a degradation model and efficient decision-making process.
