舰船内部空间有限、设备密集，频谱资源拥挤，易产生电磁耦合干扰，且海洋环境中存在各类外部电磁干扰，这些都会破坏数据链通信稳定性，导致数据包损坏，打乱数据的连续性和完整性，增加航行的风险。为此，提出复杂电磁环境下舰船航行大数据无损传输方法研究。通过分析复杂电磁环境对舰船航行大数据传输的影响，构建基于跳频频率序列的舰船抗干扰通信函数，排查干扰信号以实现干扰拦截。基于此，采用基于AES算法的无损传输方法，结合AES轮次转换加密与数字签名技术，完成数据加密传输与身份认证。实验结果表明，该方法应用后，数据传输峰值信噪比稳定维持在30 dB以上，满足无损传输要求，且通过数字签名实现合法身份强校验，有效防范非法访问，实现了复杂电磁环境下舰船航行大数据的无损传输。
The internal space of ships is limited and densely equipped, with crowded spectrum resources, which easily leads to electromagnetic coupling interference. Moreover, various external electromagnetic interferences exist in the marine environment, all of which can disrupt the stability of data link communication, cause data packet damage, disrupt the continuity and integrity of data, and increase the risk of navigation. Therefore, a lossless transmission method of ship navigation big data in complex electromagnetic environment is proposed. By analyzing the influence of complex electromagnetic environment on ship navigation big data transmission, the ship anti-interference communication function based on frequency hopping frequency sequence is constructed, and the interference signal is checked to realize interference interception. Based on this, a lossless transmission method based on the AES algorithm is adopted, combining AES round transformation encryption and digital signature technology to complete data encryption transmission and identity authentication. Experimental results show that after the application of this method, the peak signal-to-noise ratio of data transmission is stably maintained above 30 dB, meeting the requirements of lossless transmission. Moreover, strong verification of legitimate identities is achieved through digital signatures, effectively preventing illegal access, and realizing lossless transmission of ship navigation big data in complex electromagnetic environments.
