查询词典 Loran

Loran Navigate Mathematics Method.

罗兰导航数学方法。

As we known, common Loran - C receiver employs a fixed da- tum - mark in order to avoid interference caused by skywave, as the SNR is often poor at this point due to the amplitude limit of the pulse envelope, so it greatly increases time for tracking the datum - mark.

常规接收机为了防止天波干扰，将基准点设置在一个固定位置上，导致基准点处信噪比受包络限制而较低，从而大大增加了对准基准点的时间。

本论文的主要研究目的是提高和改进罗兰C授时能力。

Improving and ameliorating the ability of Loran-C for time service are the main objective of our study in this paper.

本论文的主要研究目的是提高和改进罗兰C授时能力。

This paper uses spectrum analysis technique for estimating the Loran-C skywave delay s.

使用现代谱估计技术进行罗兰C接收机的天波延迟估计，有效地解决了常规接收机基准点固定的问题。
