查询词典 loran

According to the typical configuration of surface ships, dead—reckoning/ Loran C integrated models are presented. An iterated filter algorithm with corelated noise, modified nonlinear Extended Kalman Filter , is deduced.

根据水面舰艇的典型配置，建立了推算艇位／罗兰c组合系统模型，推导了改进的非线性推广卡尔曼滤波——噪声相关的迭代滤波算法。

Currently there are two kinds of radio navigation resources in our country. One is the Changhe Ⅱ loran, which mainly overlays inshore regions of our country and serves for ships. The advantages of this system include the strong transmitting power, the wide overlaying region, and simple receiving technique.

我国目前现有的无线电导航资源有两种：一个是"长河二号"无线电远程导航系统，主要覆盖我国近海区域，主要为舰船提供导航，该系统发射功率大，覆盖广，接收技术简单，其缺点是导航精度低，在两个台链的结合部会出现盲区。

The same storm disrupted shortwave radio transmissions, cripple Coast Guard loran navigation systems and had automatic garage doors opening on their own

这次太阳风暴同时还使无线电短波通讯中断，海岸警卫队的洛兰远程导航系统瘫痪，车库的自动门自行开启。

His article concisely introduces the basic principle which single-chip micro-computer MCS-51 make application for the measurment of time difference and display-ing circuit in Loran A navigator,the design 0f hardware and software in system.

MCS－51单片机在劳兰A定位仪中的应用阮金珍（厦门水产学院机电工程系，厦门361021）摘要：本文简明地介绍MCS－51单片机应用于劳兰A定位仪时差测量和显示电路的基本原理、系统硬件结构和软件设计。

The report has presented detailed research on concerned instances of integrated navigation and compared it with the system of the subsonic vehicle. The research has shown that the scheme composed of Changhe Ⅱ loran, Beidou satellite navigation system and GNSS for such subsonic vehicles is feasible and technically realizable.

本文对有关组合导航的实例进行了详细研究，与亚音速飞行器组合导航系统进行了比较研究，表明亚音速飞行器采用"长河二号"无线电导航系统、"北斗"卫星导航系统和全球卫星导航系统进行组合导航是切实可行的，在技术上是完全可以实现的。

Rather than rely on self-control in situations where temptations arise, the best way to stay in control is to avoid those situations altogether, says psychologist and lead researcher Loran Nordgren, PhD, of Northwestern University's Kellogg School of Management.

心理学家以及首席研究员，西北大学Kellogg管理学院的Loran Nordgren博士指出，保持自制力最好的办法就是远离那些诱惑，而不是面对诱惑考验自制力。

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。

A novel signal processing technique using the Eigenvector algorithm for estimating sky wave delays in Loran-C receiver has been presented in this paper.

提出了一种基于特征向量算法来估计Loran-C接收机天波延迟的信号处理新技术，为设计具有自适应调节最佳采样点的Loran-C接收机打下良好的基础。
