控制电磁频谱权成为控制信息权的核心,战场频谱管理是夺取控制电磁频谱权的重要保障。电磁频谱监测与管理系统中需要进行频谱信息的传输,而数据传输系统就是实现这个功能的关键。由于海上气象条件复杂,网络信号稳定性不佳,舰载电磁监测设备远离海岸而且机动性强。针对这一点,提出了一种基于OFDM技术与移动自组网技术的海上频谱感知传输系统,完成监测信息的远程实时传输。
Controlling the power of electromagnetic spectrum becomes the core of controlling the right of information. The battlefield spectrum management is an important guarantee to seize the right to control the electromagnetic spectrum. The electromagnetic spectrum monitoring and management system needs to transmit the spectrum information, and the data transmission system is the key to realize this function. Due to the complicated meteorological conditions at sea and the poor signal stability of the network, the shipboard electromagnetic monitoring equipment is far away from the coast and has strong maneuverability. In view of this point, this paper proposes a maritime spectrum sensing transmission system based on OFDM technology and mobile ad hoc network technology to complete the remote real-time transmission of monitoring information.
