摘要
吊放声纳系统仿真是直升机反潜作战模拟的关键。分析了吊放声纳发现判决方程、各种搜潜方法的共性特征,在此基础上将探测、发现目标的问题逐步转换成易于求解的数学模型。以单机和单潜作战对抗过程为典型实例,研究了仿真系统功能需求及总体结构。讨论了基于水声资料库、DirectSound技术、实时3D效果控制,实现音频信号的合成和回放的方法。针对一个合理的数据结构对于有效的数据处理的重要性,将空间矩阵法引入吊声数据处理仿真。运行和使用表明,仿真系统为直升机反潜综合战术模拟训练提供了实用的平台。
Dipping sonar system simulation is a key problem in helicopter anti - submarine simulation. By discussing the identification equation of submarine searching, and common characteristics of search methods, a simple mathematic searching model for dipping sonar is given. Furthermore, the anti - submarine warfare based on a single - helicopter and a single - submarine is taken as a typical instance, and the architecture and functional requirement of the system are explored. By creating the underwater acoustical signal database and using DirectSound technology, the real - time audio signal is synthesized, and real - time three - dimensional sound effect is implemented. Since a suitable data structure is significant to sonar data processing, the space matrix algorithm is introduced. So far the simulation system has been put into practice, simulation test shows that the simulator provides a deeper insight into the synthesis tactical training.
