An Assessment Model for the Continuous Working Ability of Radars

摘要

Radars are the eye and ear of military equipment. The continuous working ability of a radar is to the key to guaranteeing combat effectiveness. This work proposes an assessment model of continuous working ability (CWA), based on minimal order statistics, to ensure the stability and reliability of a radar. The relationship between CWA and mean time between failure (MTBF) is analyzed to reduce the time and cost of reliability testing. Maintainability and testability are developed in expanded CWA models. Using the models, the CWA of a radar is verified considering its maintainability or testability. Finally, the relationship between CWA design, basic reliability, maintainability, and testability is examined. Methods for improvement of CWA are also introduced.
