研制先进军用无人机

This is no ordinary drone. It is designed to detect and attack an enemy UAV in mid-air. Shim Hyun-chul, and his team of students are testing this new technology that could one day be used by the South Korean military. Shim has the unmanned system research group at the science and technology graduate school KAIST.

这不是普通的无人机。它可以在空中侦测和攻击敌方的无人机。沈海准和他的学生团队正在测试这一新技术，韩国军队有朝一日可能装备这种无人机。沈海准是韩国科学技术院科技研究所无人驾驶系统研究小组的负责人。

He said these days drones can be made by anyone.

他称当今谁都可以制作无人机。

The fear is that the drones are very easy to build.They can do a lot of things. It actually appears as a very new threat.

人们担心，无人机很容易建造。而且可以用来做很多事。这看来构成一个新威胁。

And in South Korea, that threat comes from the North.

在韩国，这个威胁来自朝鲜。

North Korea’s military power was on display at a recent celebration in the capital, Pyongyang. That included what appears to be a fleet of drones, some of which might already have crossed the border.

朝鲜最近在首都平壤庆祝执政党70周年的阅兵式上展示了它的军力。包括看来是一支无人机部队，其中一些无人机可能已经飞到过韩国边界一侧。

South Korea’s defense ministry says that since 2014, it has recovered four crashed North Korean drones.

韩国国防部表示，自2014年以来，发现了四架坠毁的朝鲜无人机。

One of these small UAVs reportedly flew a reconnaissance mission over downtown Seoul. While these appear to have only taken pictures, some security analysts worry that weaponized drones could come next.

其中一架小型无人机据说在首尔市中心的上空进行过侦察。这些无人机虽然看来只是拍摄照片，但是一些安全分析人士担心，接下来的有可能是武装无人机。

文桑慕是首尔韩国战略研究所的安全分析专家。

We did not expect that North Korea could make such small drones and avoid our radar. South Korea must come up with a new security plan to detect these drones quicker and attack them.

我们没有想到朝鲜能够制造出能够躲避我方雷达跟踪的小型无人机。韩国必须制定一个新的安全计划，更快地侦测和攻击这些无人机。

And that could start with the attack drones that Shim Hyun-chul and his team are working on. Shim said confronting North Korea’s or any enemy’s UAVs will not be easy.

这个计划可能会从沈海准和他的团队正在研制的攻击无人机开始。他说，对抗朝鲜或者任何其他敌人的无人机并不容易。

Drones are very small, drones are very hard to detect, even if you detect it there are very few things that can be done.

无人机体型小，雷达很难侦测，即使侦测到，也基本上无能为力。

Shim said all his team can do is perfect its drone technology faster than the enemy perfects theirs.

他说他的团队能够做的就是比敌方更快地完善无人机技术。
