| 摘 要： | 本文对AIS（Automatic Identification System）信号海上传播二次相位因子的预测算法进行研究.在深入研究海面参数对AIS信号二次相位因子影响的基础上，给出AIS频段的反射系数；在综合分析海水温度、盐度、收发天线高度和传播距离长度对AIS信号二次相位因子影响的结果下，给出不同海态时AIS信号的二次相位因子.研究结果将有助于AIS信号沿海面传播延时的高精度测量.

| Abstract: | A prediction algorithm of the secondary factor for automatic identification system (AIS)signal propaga-tion is studied.The reflection coefficient on AIS band given is derived based on the in-depth study of the effects for sea sur-face parameters on the secondary factor of AIS signal.The secondary factor of AIS signal in the different sea states is given under the influence of the sea temperature,salinity,the height of antennas and the length of propagation distance.The results will contribute to the high-precision measurement of the propagation delay for AIS signal along the sea. |
