Research on the Health Status Assessment Method of Radar Receiver Based on Health Index

The health status assessment of radar is the foundation for predicting radar status trends and conducting predictive maintenance. With the increasing functionality and complexity of radar systems, traditional health assessment methods based on mechanisms or mathematical statistics are becoming increasingly unable to accurately evaluate the health status of radar. This article proposes a component-level health status assessment model for radar receivers based on the variable weight synthesis method. It also introduces a data-driven system-level health status integration method based on a sample dataset of health indicators. This provides a basis for the formulation of subsequent maintenance strategies.
