Health Assessment of Mission-oriented TT&C Antenna

Abstract

To solve the problem that it is difficult to quantitatively evaluate the health status of TT&C antennas and that the health status cannot be effectively associated with the ability to perform tasks, this paper proposes a systematic evaluation method for the health management of aerospace TT&C antennas based on the functional mission of TT&C antennas, which closely associates the equipment health status with the ability to perform tasks. According to the functional mission of equipment, the overall health level is evaluated through the health status of the underlying indicators of the ability to perform tasks and equipment performance. Firstly, the assessment index system of the mission-oriented TT&C antenna is analyzed, and then the assessment of the target is decomposed into the assessment of multiple underlying indicators using the analytic hierarchy process (AHP), which is widely used in health assessment. The quantitative assessment is made according to the specific indicators of the lowest level, and their importance to the target assessment is determined layer by layer, so as to achieve the purpose of assessing the target health status. On this basis, the health level of the TT&C antenna is determined according to the maximum membership principle. The evaluation index system and method have important reference significance for the follow-up test and identification work.
