The Anti-sub Simulation System Using Dipping Sonar Based On HLA

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.
