【摘要】 直升机吊放声纳是海军航空兵实施快速、机动反潜的主要战术装备，它装配在军用直升机上，可以及时、准确地搜索指定海域内的敌方潜艇。在实际使用中，直升机吊放声纳的搜潜范围受水声环境、目标的辐射噪声与回波特性、搜潜装备的性能等多种因素的影响，每一因素的变化都将影响搜潜效果。对直升机吊放声纳搜潜系统进行仿真研究可以为装备的改进和战术的制定提供很大的帮助。本文结合某型直升机吊放声纳搜潜仿真系统研制任务，对声纳信号处理算法及直升机搜潜战术进行了研究。主要的研究内容包括： 1．基于主动声纳信号处理过程提出了声纳信号处理仿真模型，对仿真模型的方位估计精度和实时性能进行了仿真分析。然后，从信号功率的角度，运用声纳方程、运动学方程等建立声纳功能仿真模型，解决了声纳信号处理仿真模型实时性较差的缺点。 2．在分析总结几种常用搜潜战术的基础上，提出了一种较为通用的直升机搜潜战术仿真实现方法。通过使用这种方法，对典型的直升机单机搜潜战术的搜潜效率和搜潜概率进行了仿真实验，确定了适合项目使用的直升机搜潜战术及其搜潜战术的关键参数。 3．研究学习HLA相关知识，给出了一种基于HLA的直升机吊放声纳搜潜仿真系统的框架设计。 4．给出了基于HLA的直升机吊放声纳搜潜仿真系统的直升机吊放声纳邦员仿真软件的静态结构设计和动态行为设计，详细介绍了其内部各个组成部分的功能和工作流程。更多还原

【Abstract】 Airborne dipping Sonar is designed for military helicopter to find out enemy’s submarine in appointed sea area quickly. The Performance of detection of the dipping sonar are effected by many reasons, such as underwater acoustic environment, target signal and the performance of detecting equipment. So that, to improv the performance of sonar, it is very useful and necessary to constitut the anti-sub tactics and simulate the process of helicopter searching submarine by airborne dipping Sonar. This thesis explored sonar signal processing algorithms and some anti-sub tactics for purpose of serving the project of system simulation platform of dipping sonar, and its main contents are summarized as follows:1. Analyzing and comparing two models for Sonar simulation on time spending, it is proved that the model using sonar function simulation is more suitable for the project than using sonar signal processing model.2. A new method simulating the process of helicopter searching submarine was given based on studying some classical anti-sub tactics.3. A simulation platform based on HLA was discussed, which simulated helicopter searching enemy’s submarine by dipping sonar.4. The software for simulating helicopter searching submarine by dipping sonar was designed. And its structure and working process were introduced in detail.更多还原
