摘要
本文在理论研究和计算的基础上确定了罗兰c台链海上工作区地波传播修正模型的形式,并给出了参数初值选取及迭代计算的数学处理方法。通过与1988~1991年获取的海上测试数据的拟合计算确定了南海罗兰c台链海上工作区修正模型的参数。由该模型计算的时差修正值与实测值偏差的均方根值为0.2~0.3μs.
Based on theoretical research and calculation,the form of the correction model of groundwave propagation of Loran-c Chain in working zone on sea is determined and the formula of calculating the original values of parametera of the model and the method of iterated calculation of parameters are given.By fitting with the experiment data on sea measured during 1988-1991,the parameters of the correction model in working zone on sea of South China Sea Loran-c Chain are determined.The RMS of the deviation of calculated TD correction values according to the model from the measured ones is about 0.2~0.3μs.
