Problems solved by technology

[0002] The existing sonar mounted on unmanned boats has the following three problems: first, the sensor array has a single form and cannot obtain the three-dimensional sound field information of the marine environment, and the limitations of data collection directly affect the analysis results of subsequent data processing; second, the current The working mode of the sensor array is single, and each sensor cannot be individually controlled, collected and stored, and the synchronization between the sensor groups is poor, which will greatly limit the flexibility of the sonar equipment; finally, due to unmanned Due to the influence of boat motion and water flow, the sensor array formation will be disturbed. If correct data compensation is not performed, it may directly affect the accuracy of data collection.
This method has disadvantages such as long period, high cost, and prone to data loss.
