天线

The hardware of this system consists of antenna array, Doppler direction finder, system controller and display. The software-work mode controller, data processing and angle display.

整套系统的硬件部分包括天线阵、多普勒无线电测向仪、控制电路板和显示电路板，软件部分包括工作模式控制部分、数据处理部分和角度显示部分。

This paper presents the technique to solve"base-line blurring"in Adcock array interferometer and the"overhead indication"problem in Doppler direction finder.

本文利用两章的篇幅介绍了解决干涉仪测向天线的"基线模糊"的办法，以及解决多普勒定向仪"过顶问题"的办法。

There are three parts in this paper: developing of FM type signle channel Doppler duection finder; studying of FM/AM type single channel Doppler direction finder, applying moment method for antenna on direction finding system.

主要包括以下三方面的内容：（1）FM方式单信道多普勒定向仪的研制；（2）FM/AM多方式单信道多普勒定向仪的研究；（3）测向天线的矩量法研究。

A modern direction finder, as was then used for radio navigation in large passenger ships, used a steerable ring antenna to determine the airship's position from any two radio transmitters either land or ship-based.

一个现代化的方向搜索，因为当时使用的无线电导航大型客船，使用环形天线可操纵的飞艇，以确定的立场，任何两个无线电发射机或船舶或者土地为基础的。

It was equipped with all the modern radio surveillance receivers, radar detection receiver, direction finder, terminal demodulation machines, recording devices, signal analyzer and a variety of receiving antennas.

船上装备有各种现代化的无线电侦察接收机、雷达侦察接收机、测向仪、终端解调机、记录设备、信号分析仪器以及各种接收天线。

Inspection installation for loop antenna of direction finder on berth.

测向仪环状天线船台安装检查。

Simulated results show that the directivity and the gain of the array are improved.

模拟结果表明，天线阵的方向性以及增益都得到了加强。

The third part is about the research on the improvement of the directivity of antennas using wire medium.

然后研究谐振腔天线一些参数的对其频带和方向性的影响。

These are important for developing new antennas with a high directivity and a high workability.

这些结果对发展高方向性、可实用化的新型天线具有重要意义。

But for the gain and directivity performance, we must find another way, such as usingantenna array.

所以在本论文第六章，对印刷天线阵列进行了初步的研究。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
