[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.
