| 摘要: |
| 针对海洋监测中轻小型无人机抗风能力差、大范围动态监测能力不足的问题，本文以彩虹-4型中空长航时无人机为平台进行了载荷安装、电气接口及电磁兼容性设计，实现了光电吊舱、对海雷达、AIS多任务载荷的优化集成，通过开展远距离无人机通信、载荷数据与位姿信息实时同步回传、数据处理等关键技术研究，形成了一套完整的海洋监测平台软硬件系统。最后经过长时间的地面测试并在海南三亚市东部海域开展远距离飞行试验，依据应用场景及作业的紧迫程度，探索了海岛礁成图等常规监测和海上船只目标应急监测应用模式，验证了平台设计指标，其中平台续航能力优于22 h，作业通讯距离达到2 300 km，在无控条件下可见光、红外、SAR成像精度分别为15.35 m、21.09 m、6.30 m。结果表明，该平台能够满足海洋监测技术要求，具有实际应用价值。 |

| Abstract: |
| Based on the CH-4 medium-altitude long-endurance UAV,we designed the load installation,electrical interface,and electromagnetic compatibility,and realized the optimized integration of multitask loads such as a photoelectric pod,sea radar,and AIS.We formed a complete set of marine monitoring platform software and hardware systems through the research on key technologies such as developing long-distance UAV communication,the real-time synchronous return of load data with attitude information,and data processing.Finally,long-term ground tests and long-distance flight tests were conducted in the eastern waters of Sanya,Hainan,and conventional and emergency marine monitoring application modes were investigated based on the application scenario and urgency of the job to validate the platform’s design indicators.The platform endurance exceeded 22 h,the operating communication distance exceeded 2300 km,and the imaging accuracies of visible light,infrared,and SAR imaging under uncontrolled conditions were 15.35,21.09,and 6.30 m,respectively.To summarize,the platform can meet the technical requirements of marine monitoring while also being useful in practice. |
