At a zone of operations or underwater mine warfare, it's very critical for warship to be damaged by underwater mine. In order to increase survival rate of warship from threat of mine, specific signal of warship is measured. And then specific signal is treated and calibrated below the baseline. The sensors that measured the signal are installed under the sea to exactly measure. It's difficult for maintenance men to approach the underwater equipment compared with the ground equipment. It needs long time for maintaining, demands support equipments and handling equipment. And it needs people who maintain the equipment under the water. So, it's important to analysis accurate reliability and estimate maintenance period.
This paper present the reliability analysis method about array sensors under the water. The analysis object, array sensors, is set bounds to a warship signal measurement facility. At First, this study established procedure of reliability analysis about array sensors under the water and analyzed the structure of array sensors. It decided number of sensors which was depended on size of warship and selected reliability model through considering the structure and operational concept. Finally, it calculated MTBF(Mean Time Between Failures) of array sensors under the water.
