| Abstract: | The short-wave communication distance among shipborne electronic information systems will increase several times once the sea battlefield is exposed to the atmospheric duct. Meanwhile, the electromagnetic blind zone will appear within the communication distance range. Based on the strategic requirements of ocean security, this study carried out the reseacrch on the cooperative observation technology of atmospheric duct, and expounded the importance of atmospheric duct for over-the-horizon transmission and detection. We systematically summarize the observation principle of evaporation duct, surface duct and lifting duct and their conventional observation methods by studying the formation and influence mechanism of the atmospheric duct. In addition, we studid the traditional observation methods of atmospheric duct in depth and find that these methods have some limitations in observation means, accuracy, range and cost. Therefore, an atmospheric duct observation method based on multi-physical field cooperative detection is proposed in this paper, which can obtain real-time atmospheric parameters at sea and build an marine atmospheric duct prediction system by integrating various observation instruments and equipment, such as buoy network, ship network, satellite network and shore-based network. The large-scale, high-precision and real-time atmospheric duct forecasting system formed by our method is greatly significant to master air superiority in over-the-horizon radar detection and stealth penetration operations in the sea. |
