Enhancing the submarine's navigation and positioning system through artificial intelligence is crucial to improving the submarine's concealment in enemy waters. The following is a detailed introduction: 1. **Terrain matching navigation** - **Principle**: Use artificial intelligence algorithms to accurately model and analyze the submarine terrain data in the submarine navigation area. During the voyage, the submarine obtains the submarine terrain information of the current location in real time through sonar and other equipment, and compares it with the pre-stored terrain model. - **Advantage**: It can greatly improve the navigation accuracy, so that the submarine can accurately navigate in complex submarine terrain without relying on external signals, reducing the risk of being detected by the enemy and enhancing concealment. 2. **Target identification and avoidance** - **Principle**: With the help of artificial intelligence's image recognition and pattern recognition technology, analyze the marine environment images and signals obtained by sonar, periscope and other equipment. Quickly and accurately identify various underwater targets, such as enemy ships, submarine obstacles, etc. - **Advantage**: So that the submarine can adjust the navigation route in time, effectively avoid potential threats, and avoid losing concealment due to collision or exposure of the whereabouts. 3. **Adaptive Path Planning** - **Principle**: Taking into account multiple factors such as the ocean environment and enemy anti-submarine deployment, the optimal navigation path is generated in real time using artificial intelligence algorithms. During navigation, the path is dynamically adjusted according to real-time changes. - **Advantage**: It enables the submarine to always sail in the area with the best concealment, reducing the probability of being discovered by the enemy. 4. **Multi-sensor Fusion** - **Principle**: The data of multiple sensors such as sonar, inertial navigation system, and satellite positioning are fused and processed. The fused data is analyzed and understood using artificial intelligence algorithms to improve the accuracy and reliability of navigation and positioning. - **Advantage**: It effectively makes up for the limitations of a single sensor, reduces navigation and positioning errors caused by sensor errors or failures, and enhances the survivability and concealment of submarines in complex environments. 5. **Intelligent Noise Control** - **Principle**: The noise characteristics generated by the submarine itself are analyzed through artificial intelligence algorithms, and corresponding noise reduction measures are taken. Intelligent regulation of the submarine's mechanical system, propulsion system, etc. is carried out to reduce the noise level. - **Advantage**: Reduce the noise signal generated by the submarine when sailing underwater, reduce the possibility of being detected by enemy sonar, and thus improve the submarine's stealth.
