摘　　要：为降低卫星在船舶自动识别系统(Automatic Identification System,AIS)载荷频段电磁干扰处理工程实施代价,打破近海海域接收屏障,文章提出了AIS赋形高增益梯度天线、AIS抗电磁干扰与连续捕获等载荷优化方法,并开展了整星AIS频段电磁环境优化设计与处理。相关优化措施的有效性在卫星地面测试过程得到了验证,卫星入轨后,AIS载荷可适应卫星工作工况,在轨接收效能得到进一步验证。结合海洋二号C(HY-2C)卫星AIS载荷在轨表现,分析了AIS数据应用情况,给出了后续AIS载荷在设计及工程上的优化建议。In order to reduce the cost of implementing the satellite electromagnetic disturbance processing project in the Automatic Identification System(AIS)onboard frequency band and break the reception barrier in the offshore sea,this paper proposes the onboard optimization methods of the AIS high-gain gradient antenna,the AIS anti-electromagnetic interference,the AIS continuous acquisition design and processing of the satellite electromagnetic environment in the AIS frequency band.The effectiveness of relevant optimization measures are verified in the satellite ground test process.After on-orbit,the AIS load can adapt to the working condition of the satellite and the receiving efficiency is further verified.Combined with the performance of HY-2C satellite AIS,the application of AIS is analyzed,and suggestions on the design and engineering optimization of AIS loads are given.
