摘　　要：在复杂的海上环境中,舰载超短波电台面临着多种因素的挑战,因此对编码调制可靠性提出了更高的要求。为此,实施舰载超短波电台编码调制可靠性测试研究。船舶搭载舰载超短波电台在所选择的三个实验区域内进行可靠性测试,测试在电磁干扰环境和多径效应环境下的误码率、信噪比和频谱效率。结果表明:海域2相比海域1和海域3,误码率相对较高。相比海域1和海域2,海域3在多径效应环境下,信噪比相对较低。海域1、海域2在电磁干扰环境下,频谱效率相对较低,其他环境海域下频谱效率相对较高。In complex marine environments,shipborne ultra short wave radio stations face various challenges,therefore higher requirements are put forward for the reliability of coding and modulation.To this end,research on the reliability testing of encoding and modulation for shipborne ultra short wave radio stations is being carried out.The ship is equipped with a carrier based ultra short wave radio station for reliability testing in three selected experimental areas,to test the bit error rate,signal-to-noise ratio,and spectral efficiency in electromagnetic interference and multipath effects environments.The results show that compared to Sea 1 and Sea 3,Sea 2 has a relatively higher error rate.Compared to Sea Area 1 and Sea Area 2,Sea Area 3 has a relatively low signal-to-noise ratio in a multipath effect environment.In the electromagnetic interference environment,the spectral efficiency of Sea Area l and Sea Area 2 is relatively low,while in other environmental waters,the spectral efficiency is relatively high.
