【摘要】:本文對AIS(Automatic Identification System)信號海上傳播二次相位因子的預(yù)測算法進行研究.在深入研究海面參數(shù)對AIS信號二次相位因子影響的基礎(chǔ)上,給出AIS頻段的反射系數(shù);在綜合分析海水溫度、鹽度、收發(fā)天線高度和傳播距離長度對AIS信號二次相位因子影響的結(jié)果下,給出不同海態(tài)時AIS信號的二次相位因子.研究結(jié)果將有助于AIS信號沿海面?zhèn)鞑パ訒r的高精度測量.
[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.
