Commonly used methods of quadrature coherent detection are summarized, as well as their

建立雷达系统的各个模块后，对整个雷达系统的高重频工作模式进行了仿真测试，表明该系统能够有效地抑制杂波、检测目标。

From the view of the challenge faced by modern radar, it is an important and valuable work to explore"counter-stealth"impulse rada...

从现代雷达所面临的挑战来看，积极开展冲激雷达反隐身研究是一项重要而有价值的工作。

In 1960, the FAA began successful testing of a system under which flights in certain positive control areas were required to carry a radar beacon, called a transponder, that identified the aircraft and helped to improve radar performance.

1960年，联邦航空局进行了一项成功的试验，在特定管制空域内的航空器安装了一个称作应答机的雷达信号装置。它能够用于航空器识别并增强雷达的性能。

It is of necessity to research non-cooperative bistatic radar to enhance the performance of radar fence.

为了提高整个雷达网的性能，有必要重点研究非合作式双基雷达。

The radar puts out what we call a radar fence,' explains Major Matthew Morand, director of operations.

雷达提出了所谓的雷达栅栏，'解释主要马修莫朗，业务主任。

According to the multisensor multiple level parallel detection structure and combining the traditional detection mode of radar fence system, this paper advances a positive groundwork territorial radar fence system which is more close to existing equipment collocation of army. The detection capability and reliability of this system is analyzed too.

摘 要：根据多传感器多层并行检测结构理论，结合传统雷达网系统的检测方式，本文提出一种更加贴近部队现有装备部署的有源地基区域性雷达网系统检测结构，并对该系统结构的检测性能和可靠性进行了分析。

Radar signal processing is an important part of radar system.

雷达信号处理是雷达系统的重要组成部分。

The typical scenario is this: A shipboard radar operator on the destroyer DD-538 is watching his SC-2 PPI radarscope.

举个例子，DD-538上舰载雷达的操作员正在监视SC-2雷达的PPI显示器。

Using a neural network algorithm to establish a typhoon rainfall model and to seek the nonlinear relations between the relevant parameters and rainfall intensity is a rational approach. The rainfall data used in this study include rain gauge data and radar data, and is able to reflect the spatial distribution of the precipitation pattern.

雷达具有空间侦测能力，利用地面雨量计的雨量资料与雷达回波的资料，可以将空间中的降雨分布趋势表示出来；本研究当中所决定的台风降雨因子是根据过去相关研究文献所整理出来，而这些台风降雨因子是否能完全模拟台风降雨的机制，尚待观察。

Radar rainfall estimation combined with a few rain gauges has as good result as dense rain gauge network does in runoff simulation that gives a good prospect of radar application in flood monitoring and forecasting.

2雷达联合少量雨量计估测降水用于流域径流模拟时，模拟精度和用稠密雨量计网模拟的精度接近，显示雷达在流域径流模拟和洪水监测预报中有相当高的应用价值。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
