【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]:In this paper, the prediction algorithm of quadratic phase factor of Automatic identification system (AIS) signal at sea is studied. On the basis of studying the influence of sea surface parameters on the secondary phase factor of AIS signal, the reflection coefficient of AIS frequency band is given. Under the influence of antenna height and propagation distance length on the secondary phase factor of AIS signal, the quadratic phase factor of AIS signal under different sea conditions is given. The results of the study will be helpful to the high accuracy measurement of the AIS signal propagation delay along the coast.
