查询词典 navigation radar

Unifying with the distribution of polarized light,the role of maximal polarization line and imaginary pole point in navigation are analyzed in detail.

结合天空偏振光的分布情况，并详细地分析了天极点和最大偏振线在导航中所起的作用。

This system adopts Java to construct a web-based three-level architecture, which is open and strong compatible. The system creates an interactive and immersible virtual navigation world by using VRML. As a result, it allows many users to perform shiphandling and decision-making training online from anywhere, anytime. This training platform provides a portable and flexible training paradigm for maritime education and training.

该系统依托Java构建体系结构开放、兼容能力强的Web三层体系模式的仿真应用，借助VRML营造交互、沉浸表现效果的虚拟船舶操纵训练环境，允许多用户随时随地的进行船舶操纵和决策等方面的学习和训练，从而为航海教育和培训提供了一种轻便灵活的学习平台。

But, because of the policy of the Taiwanese authorities persistence "impassability pass, no inbound", although carried out a direct navigation of container transportation in partial scope, its still limited at transport cargo to go toward the third long range, the goods that with the purpose of trade with each other still need to pass through the third region.

但是，由于台湾当局坚持"不通关、不入境"的政策，虽然实现了两岸集装箱运输局部范围的直接通航，但仍局限在运输两岸中转运往第三地的远程货物，两岸间互为贸易目的的货物仍然要通过第三地中转。

Based on the analysis of navigation benefit, this paperpoints out the problems existed and the necessity of the raise of the Three Gorges Reservoir's impoundment level.

文章对此作了概略分析，并指出存在问题和及时抬高三峡水库蓄水位的必要性。

In general, the study of this article includes the areas from IMU to the inertial integrated navigation system theories and applications, and some of studies are advanced.

总之，本文的研究范围涉及了从惯性元件到惯性组合导航系统及其理论的实际应用等多个方面，并在很多方面具有一定的创新之处。

For accurate navigation, it is necessary to calibrate IMU b ias on the spot.

高精度的惯性测量组合中，现场标定零偏十分必要。

The error models of strapdown inertial navigation system are given, and error models of low cost system are given according to the specialties of low cost IMU.

列出了捷联惯导系统的误差传递方程，并结合低成本IMU的特点，给出了低成本捷联惯导系统的误差传递方程。

Methods for improving accuracy of inclinometer with inertial navigation components［J］.

Then this thesis presents another SLAM algorithm-the Relative Map Filter, The RMF is however disadvantaged by the inability to guarantee consistency of the estimated relative map. The following sections introduce a new navigation filter - the Geometric Projection Filter or GPF. The consistency of the estimated relative map is enforced by the application of the constrained estimator to an inconsistent relative map produced by a standard RMF.

然后介绍了SLAM问题的结构，分析了绝对地图滤波器的性质，介绍另一种解决方法—相对地图滤波器，但是相对地图滤波器产生不一致的相对地图，因此在相对地图滤波器的基础上应用约束估计产生一致的相对地图，这就是几何投影滤波器，从而有效的解决了SLAM问题。

The new filter not only has the advantages of the incoordinate interval filter, which can solve the local filter\'s problem that the different navigation device measurements have different periods in real system ,but also has the advantages of preventing distortion of filter which caused by the imperfect arithmetic method or the incorrect statistical characteristic of noises.

对MINS/北斗/GPS多传感器信息融合算法进行了研究，提出了一种改进的非等间隔联邦滤波器，这种滤波算法除了具有非等间隔联邦滤波器的优点即可以解决各局部滤波器的量测信息的周期不同外，还具有抑制因计算方法不完善或系统噪声统计特性不确切而引起的滤波发散的功能。
