| 摘 要： | 研究了罗兰-C天波传播时延的稳定性与空间相关性.结果表明:罗兰-C天波传播时延的稳定性存在明显的日变化,白天比较稳定,夜间较差,日出前后稳定性最差;主、副台天波时延随机起伏间的相关系数大部分时间都在0.5以上,平均为0.7~0.8.

| Abstract: | The stability and space correlation about the sky-wave propagation time-delay in Loran-C system are studied.The result indicates: the stability of Loran-C sky-wave propagation time-delay is obviously changed in a whole day,which is better in daytime,worse in nighttime,and worst at sunrise;the correlation coefficient of the sky-wave time-delay randomicity between the primary and secondary stations is upon 0.5 in many a time,its average is about from 0.7 to 0.8. |

| Keywords: | LF sky-wave time-delay stability correlation coefficient |
