Abstract: The corrosion of ground radar is introduced comprehensively and systematically in this paper by investigating the corrosion of ground radar and employing statistical analysis methods on identified corrosion points. In view of the corrosion problems and trend, the corrosion control countermeasures are put forward. In the investigation and analysis of the corrosion status, the corrosion forms of radar, the influence of environmental exposure on corrosion processes, the primary factors and stages of its development are emphatically introduced. In the analysis of corrosion control countermeasures, the requirements and methods of environmental control design, sealing design and shielding design are emphasized. Through data analysis, the corrosion trend is found, and a method system for scientific management combined with the characteristics of radar products and research development process is established. The idea of comprehensive corrosion control of the whole process and life cycle is put forward from the program design, engineering design to production and manufacture, use and maintenance, etc. Building upon a top-down approach, a theoretical framework for corrosion control for radar products is refined.
