Abstract: In order to monitor the radiation noise of submarine in the real time is come true, on the basis of basic characteristics and uses of monitoring submarine noise on-board equipments which are often used in worldwide navy were introduced, method of extracting characteristic frequency spectrum of main noise sources for submarine was studied by use of acceleration sensors, and then displaying and setting threshold of self-noise hydrophone was studied based on the condition monitoring, and setting threshold of self-noise hydrophone was studied based on far-field measurement. The results demonstrate that the characteristic spectrums of main noise sources from submarine can be picked up and threshold of self-noise hydrophone can be set by use the method of this paper, which can provide the base for monitoring the radiation noise of submarine in the real time.

Keywords: Submarine noise monitoring; Acceleration sensor; Self-noise hydrophone; Characteristic frequency spectrum; Threshold

摘要：针对目前武器装备体系能力描述精确性及规范性存在的不足，在深入研究武器装备体系能力、能力指标体系、能力关系以及能力层次结构等相关内容基础上，提出一种基于本体理论的武器装备体系能力形式化描述方法。并以空战武器装备体系超视距空战能力为例，对其进行形式化描述。实例研究表明，该方法可大大提高武器装备体系能力描述的精确性，为今后能力分析提供精确可靠的基础数据。

(School of Information System & Management, National University of Defense Technology, Changsha 410073, China) Abstract: Aiming at the lacking of accuracy and criterion of current weapon equipment system description, proposed the method of noumenon -based weapon equipment system formalization description, on the basis of researching on the weapon equipment system capability, capability index system, relations of capabilities, capability hierarchy structure etc. And taking the beyond-the-horizon air combat capability of air battle weapon equip system as example to carry out formalization description. The example shows that the method can improves the accuracy of weapon equipment system capability description. Furthermore, it can provide basic data for the capability analysis for the future.
