Research of Spectrum Perception Transmission System at Sea Based on OFDM and Ad Hoc Network Technology

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。

Control of electromagnetic spectrum become the core of control information, battlefield spectrum management is an important guarantee of seize control of the electromagnetic spectrum. The transmission of spectrum information is needed in electromagnetic spectrum monitoring system, and data transmission device is the key to achieve this functionality. Due to the weather conditions are complex at sea, the network signal stability is poor, The shipbased electromagnetic spectrum monitoring equipments are away from the coast and have strong maneuverability. Aiming at this point, the marine electromagnetic spectrum wireless transmission device based on OFDM technology and mobile ad hoe networks technology is putted forward, complete real - time transmission of information.
