Abstract: Based on contemporary radar receiver′s technical characteristics, deferring from traditional receiver health management, by analyzing the bit information of each module in the signal-flow and utilizing the function relativity between them, some health information excavated, and the system working state combined, the receiver′s health conditions are synthetically analyzed and judged. Some processing algorithms being put forth, a health management method being obtained, the accuracy, timeliness of fault diagnosis being greatly improved, the receivers′ health management usefulness gets enhanced. This technology has been put into use in a few radar receivers′ engineering developing, and fine effects have been seen, which is the ground of consequent lifetime health management of receivers and lifespan estimation and failure forenotice studies.
