New technology can provide advances in the way we do things, expanding areas previously left unexplored and simplifying previously burdensome tasks. This is true with advancements in Unmanned Aerial Systems (UAS), or drones. There are global efforts focusing on using drone technology to improve and support our everyday lives, and the commercial market is offering increasingly small, relatively inexpensive and capable drones. Given their rapid technology advancement and proliferation, the public safety and homeland security communities must address the fact that drones can be used nefariously or maliciously to hurt people, disrupt activities and damage infrastructure.
在新环境中进行测试
Since 2016, the Department of Homeland Security (DHS)Science and Technology Directorate(S&T) has focused on developing and delivering counter-UAS (C-UAS) capability technical upgrades for DHS operating components with high priority needs. S&T helps guide, advise and provide technical expertise to all components and Homeland Security Enterprise partners on the steps they can take, and available technology they can legally use to counter unwanted or malicious UAS. Most CUAS systems are still legally prohibited from operating in the national airspace, however, DHS and the Department of Justice are seeking new legal authorities from Congress to use this evolving technology as part of certain missions. As part of this work, S&T established a test and evaluation series, the城市反UAS技术的技术评估（战术）, to assess the performance and suitability of commercial counter-UAS solutions in homeland security settings.
“有一个巨大的标志et of commercial counter UAS solutions out there. But most – if not all of them – have not been subjected to testing in urban environments that are relevant to homeland security. So to date there is very little real data on the performance of these systems in urban settings,” explained S&T’s Program Executive for UAS, Anh Duong.
2017年12月，DHS S＆T的国家城市安全技术实验室（NUSTL）在位于弗吉尼亚州海军陆战队基地Quantico的城市培训中心与海军陆战队战争实验室合作，与UAS计划执行办公室的2017年计划执行办公室执行了第二部分。那里的模拟城市允许S＆T复制与国土安全行动更相关的环境。
Opportunities to Test C-UAS Systems
Nine C-UAS commercial solutions with varying types of sensors for detecting, tracking and identifying small UAS were evaluated in the week-long event. TACTIC not only allowed S&T to assess the capabilities of these technologies and collect valuable data that will feed other tools used to advise DHS components, but it also provided an opportunity for developers to see their C-UAS technologies put into action under settings that are relevant to homeland security and obtain direct feedback from potential end-users.
Nustl副局长Alice Hong表示：“诸如战术等评估为政府和行业提供了更好地了解C-UAS技术，以及我们如何共同努力为DHS和急救人员提供解决方案。”“这些评估是确保系统满足国土安全企业技术最终用户需求的关键。”
通知国土安全经营者C-UAS
国土安全部的运营组件以及其他联邦，州，地方，急救组织和国际政府代表构成了战术上约100名观察员。亲眼目睹C-UAS技术如何在复制的城市环境中工作，同时还学习与各种技术相关的物流和培训要求，与会者散发出可以为未来的技术获取，运营和培训提供依据的知识。Among the visitors to the exercise was the White House Deputy Chief Technology Officer and Assistant to the President and staff from the White House Office of Science and Technology Policy, as well as S&T’s own Senior Officer Performing the Duties of Under Secretary for Science and Technology, Mr. William Bryan.
Duong说：“我们对白宫和国土安全部S＆T的高级领导层的访问感到特别满意，并感谢DHS运营组件中客户的热情参与。”“他们的存在强调了反UAS任务的重要性以及DHS S＆T所做的有影响力的贡献。”
Collecting UAS Data Efficiently
For any test and evaluation effort, data collection is paramount. TACTIC requires a wealth of data—information collection from the test environment, C-UAS systems evaluation, and flight of the UAS. To accomplish this, S&T funded the Stevens Institute of Technology to develop and outfit an Instrumentation Van (I-Van) that serves as a portable C-UAS data collector. Loaded with equipment such as spectrum analyzers, GPS trackers, cameras, acoustic sensors, and weather devices, this instrumentation van is the first of its kind and enables highly efficient and accurate data collection.
Use of the I-Van is just one part of an effort to maximize efficiency through standardized data collection. S&T is also pursuing common test methods and protocols among agencies and international partners to reduce costs and facilitate data sharing.
“我们预计将不时将测试从模拟城市转移到真正的城市。我们也希望看到更高级的反UAS技术。”杜恩谈到未来的战术练习时说道。尽管此策略事件没有评估缓解技术，但Duong表示可以在未来的活动中添加它。
通过技术发展安全性
“ UAS技术正在快速发展。无人机变得非常便宜并且非常有能力。更重要的是，坏人甚至可以使用3D打印机来制造无人机。我们不能指望知道每架无人机，因为它可能不会在商业上购买而是私人建造，” Duong强调。“因此，从我们能够对抗它们的角度来看，我们必须能够预料到技术的去向，从而相应地孵化对策。”
Technology assessments, efficient data collection, and development of C-UAS tools support DHS operating components and partners in their quest to plan for and deploy the most effective capabilities against nefarious UAS that threaten the people and critical infrastructure of our nation.
