美国军方正在美国中西部6个州，使用高空气球，进行大范围监控测试。 据英国《卫报》爆料，美国联邦通信委员会（Federal Communications Commission）的文件显示，美国军方正在中西部的南达科他、明尼苏达、爱荷华、威斯康星、密苏里、伊利诺伊6个州范围内，使用实验性高海拔气球进行广域范围的监控测试。

The tests, which have not previously been reported, received an FCC license to operate from mid-July until September, following similar flights licensed last year. 气球上装有高科技雷达，可以在任何天气条件下，不分昼夜地同时跟踪许多车辆。这些测试此前从未被报道过。这些测试获得了联邦通讯委员会的许可，测试可以从7月中旬一直持续到9月。去年也有类似的测试行动。 Arthur Holland Michel, the co-director of the Center for the Study of the Drone at Bard College in New York, said, “What this new technology proposes is to watch everything at once. Sometimes it’s referred to as ‘combat TiVo’ because when an event happens somewhere in the surveilled area, you can potentially rewind the tape to see exactly what occurred, and rewind even further to see who was involved and where they came from.” 纽约巴德学院无人机研究中心的联席主任阿瑟·霍兰德·米歇尔说，“这项新技术的目的是要同时观察所有东西。有时它被称为“战斗TiVo”（TiVo是美国数字录象机设备，能帮助人们录下和筛选电视上播放过的节目），因为当一个事件发生在被监视区域的某个地方时，你可以倒带，看看到底发生了什么，甚至可以倒回去，看看谁参与其中，他们来自哪里。” ▲Pentagon testing mass surveillance balloons across the US (via The Guardian)

The loadout includes a synthetic aperture radar designed to be able to detect every single moving car or boat active in a 25-mile field beneath the balloon. 这些气球还携带装有传感器和通讯设备的小型运载工具。载荷包括一个合成孔径雷达，设计用来探测气球下方25英里区域内移动着的每一辆汽车或每一艘船只。 The craft operate as a network, fitted with advanced mesh networking technologies meaning they can communicate with one another. The balloons can pass information—including video—to each other and to receivers on the ground. 这些气球配备了先进的网状网络技术，运作起来成为一个网络，意味着它们可以彼此通信。气球可以互相传递信息，包括视频，也可以传递给地面上的接收器。 The Guardian suggested the balloons may be carrying Sierra Nevada's advanced Gorgon Stare video capture system, which is already in use in U.S. military drones. The Pentagon has also used Gorgon Stare on surveillance blimps in Afghanistan. It consists of nine cameras recording panoramic images, enabling operators to capture activity across an entire city at once. 《卫报》表示，气球可能携带内华达山脉公司先进的“戈尔贡凝视”视频捕捉系统，该系统已经在美国军用无人机上使用。在阿富汗，五角大楼还在监视飞船上使用“戈尔贡凝视”。它由9个摄像机组成，可以记录全景图像，使操作者能够同时捕捉整个城市的活动。 ▲Pentagon Is Testing High Altitude Surveillance Balloons to 'Watch Everything at Once': 'It's Disturbing' (via Newsweek)
