I want to bring to your attention the features that make Groundvue stand out from its competitors. The radars that we produce are the result of over 30 years experience in designing all sorts of radars. Unlike our competitors, we do not produce radars as a by-product of other geophysical tools. We are radar specialists.

 

 

 

 高质量数据—比其他雷达系统数据质量高很多

Groundvue radars are fully screened. Other systems say they are shielded but they are not fully screened, leaving open the possibility of clutter from surrounding objects and even the operator. Clutter obscures the real targets. The Groundvues have full metallic screening around each part of the antenna so that the signals are transmitted into the ground and the reflected signals are all from buried targets.

 

Groundvue 是全屏蔽雷达。其他雷达系统声称他们是屏蔽的但实际上并不完全是屏蔽的，杂波有可能向周围的目标甚至向操作员扩散。杂波会干扰真正的目标体。Groundvues 系列在天线每一部分都带有全金属屏，以便信号传入地下和并从掩埋的目标返回。

All of the Groundvue radars have twin arrayed antennas. The radar beam is a cone shape. The deeper that you look, the wider the spread of the beam. Twin arrayed antennas focus the beam more sharply, making it easier to detect targets. They also result in increased signal transmission into the ground. This is very important. The greater the signal transmitted into the ground, the greater the returned signal and the easier it is to detect targets.

 

所有的Groundvue 雷达都有双排天线。雷达波束是椎体形状。探测的越深，波束伸展的越宽。双排天线集中光束越强烈，探测目标就更容易。双排天线也可以增加到地下的信号传输。这一点非常重要。传入到地下的信号越强，返回的信号就越强，也越容易探测到目标。

Another way in which we ensure that our data quality is much better than any of our competitors is by special design features in the receiver:

另外,我们保证,用我们的系统获得的数据质量要比其它竟争者要好很多，这要源于我们特殊的接收机性能设计.

1.                  The repetition rate at 2MHz to 500GHz is far higher than any other system; 

在2MHz 到500GHz 的天线中，重复频率要高于其他的系统。

2.                  We use true 16 bit A/D converters with very high linearity. This allows our radars to detect small targets more easily.

我们使用高线性的16 bit A/D 转换器。这使得我们的雷达更容易探测到细小目标。

 

Groundvue cables are damped to give noise free operation. The results are as good as using fibre optic cables but the cables are much stronger. Fibre optic cables are notorious for their fragility.

特制的Groundvues 电缆在操作时候是无噪音的。得到的结果与使用纤维光缆得到的结果一样好，但我们的电缆要结实一点。纤维光缆的缺点是很脆弱，容易遭到破坏。

Of all the radar systems, Groundvue makes use of the widest bandwidth. The industry norm for the ratio of top frequency to bottom frequency is 2:1. For Groundvue, this ratio is 3:1. Our target definition is much better. It also means that you do not need to change antenna frequencies so often as there is a better overlap between the frequency ranges. This saves you money also. You may not need as many antennas. This saves you time – complete 1 survey, not 2.

在所有雷达系统中，Groundvue 使用最宽的带宽。行业规范规定的最高频率到最低频率的比率是 2:1。对于Groundvue，比率是3:1。因此，我们的目标界定要更好。也就意味着你不用频繁的更换天线，因为在这个频率范围里有更好的重叠性。这也节省了你的金钱。而且也不需要用许多的天线，很省时间—就能完成1次测量，而不是2次。

Radars measure in time. Some of the radars on the market, some of those widely sold do not have a stable time base. Groundvues have the most stable time base of them all. Please do not take my word for it. The UK Highways Agency commissioned TRL Ltd (the UK Transport Research Laboratory) to measure the time performance of all radars being used on the road network. Groundvue was awarded the maximum 3 stars. If the time base is not stable, you cannot measure depth with any accuracy. You may think you have a target but you have no means of knowing what you are measuring.

 

雷达测量及时。市场上一些雷达，有的连稳定的时基都没有就被大量的出售了。Groundvues 拥有最稳定的时基。.英国高速公路处委任英国运输研究实验室在公路网路上测量了所有雷达时间性能。授予Groundvue 为最高的3颗星。如果时基不稳定，任何深度的准确性都是不可能的。你会认为:有一个目标体,但不知道用什么方法来测得它是什么。

We eliminate noise & clutter inside the hardware.   This gives you the best possible

view into the ground when you carry out a GPR survey. It makes processing much easier and quicker. In short, it saves you time and money.   Buying an inadequately screened radar or one which does nothing to cut down its own internal noise may be a costly mistake.

在硬件内部,我们做了噪音和杂波消除设计。当我门进行GPR测量时，会给你提供最有可能的进入地下的视角。这使得处理过程更容易，快速。简言之，省时又经济。买到一套不适当的屏蔽雷达或它本身不能削减内部噪音的雷达，将会是昂贵的错误选择

2.      User Friendly Equipment 

Our equipment has an easy to understand user interface. The data is always recorded raw. Gain parameters are for viewing only. So, if your operator makes a mistake, so long as he or she has selected the correct depth and the correct sampling interval, there is no need to carry out the survey again. This is not the case for our competitors. You have to select your gain parameters (for example) and they cannot be changed. 

仪器的用户界面很容易理解。并总是记录初始的数据 。增益参数也能看到.因此,如果操作员作了误操作，只要他选择了恰当的深度和采样间隔，不需要进行再次测量。我们的竞争者却没有这种案例，比如，你不得不选择你的增益参数，并且这些参数不能改变的。

Most radar systems allow you to add 1 marker to the data. We allow you a minimum of 4 (using the datalogger) and a maximum of ……….any key on the keyboard of the laptop. You can use different markers to indicate survey boundaries; problems on the ground; known features of the site etc.

大多数雷达系统允许在数据上加上1个标记。我们的雷达最少允许作4个标记（使用数据记录器），最大是笔记本电脑键盘上的任何键。你可以使用不同的标记来说明测量的边界，地面上的问题，现场的已知特征等。

 

 操作快速

Most companies selling radars quote their single channel system at speeds up to 1000 scans/sec. Not all of them can achieve this rate. This is single channel operation. They keep very quiet about their multi-channel operation. Their antennas are fired in sequence, not simultaneously. The more channels you use, the slower the systems becomes. Groundvue 3 is the fastest operating multi-channel on the market. Our antennas are triggered simultaneously. Our 4 channel speed is equivalent to 1000 scans/sec. No other company has managed to match this. The picture shows 3 different configurations of Groundvue 3 on the roads where it is used at traffic speeds. To show you how r ed it is, there is also a picture of the same system being used on a cliff face in the desert in Oman. 

大多数公司在销售他们的雷达时，报的价都是单通道系统，说速度可达每秒1000扫。实际上，并不是所有的雷达都能达到这个速率。这只是单通道操作，他们会在多通道操作方面保持沉默。他们的天线是按顺序点火，而不是同时。使用的通道越多，系统会变得越慢。Groundvue 3 是市场上操作最快的多通道系统。我们的天线是同时触发的，4通道速度相当于1000 scans/sec。其他公司很难与此相比。这张图片显示的是Groundvue 3的3个不同的配置，都是以交通流量的速度用于公路测量。我们可以看到路面是非常粗糙的。还有一张图片，地点是在阿曼一个沙漠悬陡峭面上（位于阿拉伯东南部沿海地区），使用的也是Groundvue 3系统。

Groundvue 3 is used for every possible application, slow or fast in all kinds of environments.  It can be used as a single channel system, a two channel system, a three channel system or a four channel system. There is a very wide range of frequencies available – 250MHz, 400MHz, 1GHz, 1.5GHz, and 4GHz. Depending on the soil environment, this gives depth ranges of 0.5m down to at least 10m. There are also some specialist antennas which no other radar company can provide. 

Groundvue 3 可以在各种可能的环境下应用，不同的环境速度有快有慢，因此测量深度可以从0。5米到至少10米。可以作为单通道系统，双通道系统，三通道系统或四通道系统来使用。可用的频率范围非常广—有250MHz, 400MHz, 1GHz, 1.5GHz, 和 4GHz. 依据土壤环境，可以得到0.5米到10米的探测深度。还有一些其他公司不能提供的特殊天线。

 

5.                  Technical Advantages: Low Frequency Applications

The Groundvue low frequency radars have much better depth penetration than those of competitor companies. Groundvue 2 (30MHz to 100MHz), shown here working in the deserts of Oman can reach a full 10m more in limestone karst than the equivalent Pulsekko. This test carried out independently by Heriot Watt university Institute of Petroleum studies, convinced them to change radars. In place of the 20m they previously achieved, Groundvue 2 gave them a full 30m depth of data. They now use Groundvue for a clearer signal and better depth penetration.

Groundvue低频雷达比其他雷达产品有更好的穿透性。（频率从30mhz至100mhz ），在阿曼的沙漠中的石灰岩溶洞中，探测到一个完整的10米以上的深度，优于同样的Pulsekko系统。这项测试由Heriot Watt大学石油研究所独立进行，说服了他们使用我们的雷达。在他们之前只能查看到的20m深度的地区， groundvue2给了他们清晰的30米深度的数据。于是他们现在使用Groundvue雷达能得到更清晰的信号和更好的深度渗透。
