Mission Reliability Evaluation of Shipborne Radar Based on Mission Profile

When the shipborne radar carries out the combat mission, its mission reliability is greatly affected by the combat environment and combat mode. Based on the characteristics of shipborne radar fault data recording, this paper proposes a mission reliability assessment method based on mission profile, and finely evaluates the reliability level of different mission profiles of shipborne radar. Firstly, the fault information matrix of the shipborne radar is defined; secondly, the failure rate in the time period is equivalently converted into each section according to the equivalent reduction coefficient, and the mission reliability model of the shipborne radar is established; similarly, the proposed section is proposed the mission reliability evaluation method below realizes the reliability prediction of the expected mission profile. Finally, the actual operation fault data of a certain type of shipborne radar is taken as an example to analyze the difference between traditional reliability evaluation and the method in this paper. The results show that the mission reliability assessment method of shipborne radar based on mission profile is reasonable and feasible, and it can effectively assess the reliability of different mission stages.
