项目摘要
This project aims at providing an effective engineering solution to the increasing acts of armed violence in public spaces - a trend which is of great concern to security professionals and civilians alike. If terrorist or criminal agendas are the motives, prevention is difficult but possible. The acts of lone active shooters, however, are practically impossible to prevent.** Our objective is to give the public and law enforcement means of protection through early warning. We will develop market-ready prototypes of compact portable (possibly wearable) radars for the stand-off detection of on-body concealed weapons such as knives, handguns, rifles, grenades and explosive vests. Our prototypes will feature automated unsupervised operation and ability to operate in diverse environments. Moreover, they will be much smaller and significantly less expensive than existing concealed weapon detection systems. The major advantage is that screening is performed while the person is moving freely. The person's cooperation or awareness of the screening is not necessary. In addition, the detection systems will have cognitive ability based on machine learning. This will ensure agile response to interference and changes in the environment along with ability to "learn" about new threats. In one application, an extra low-power prototype aims at short-range (0.5 to 3 m) detection. Deployment of multiple units in public spaces such as schools, malls, transportation nodes, and stadiums will provide around-the-clock surveillance for body-worn weapons. In a second application, a higher-power prototype will provide stand-off detection at distances as large as 15 to 20 meters. It is intended for police or security professionals either in a portable or a wearable form.** The system detects threats by analyzing radar signals, not images. Thus, there are no privacy concerns. The detection outcome is a warning signal that triggers automatically user-defined responses (e.g, taking a photo of the scene or messaging security). Our devices use microwaves, which are non-ionizing and weaker than those of a mobile phone, ensuring the public safety.****
该项目旨在为公共场所日益增多的武装暴力行为提供有效的工程解决办法,这一趋势引起安全专业人员和平民的极大关注。如果动机是恐怖主义或犯罪,预防是困难的,但也是可能的。然而,单独行动的枪手的行为实际上是不可能阻止的。**我们的目标是通过预警为公众和执法部门提供保护手段。我们将开发面向市场的紧凑型便携式(可能可穿戴)雷达原型,用于远距离探测身上隐藏的武器,如刀、手枪、步枪、手榴弹和爆炸背心。我们的原型将具有自动无监督操作和在不同环境下操作的能力。此外,它们将比现有的隐蔽武器探测系统小得多,价格也低得多。其主要优点是在患者自由活动时进行筛查。这个人的合作或意识的筛选是不必要的。此外,检测系统将具有基于机器学习的认知能力。这将确保对环境中的干扰和变化的敏捷响应,以及“学习”新威胁的能力。在一个应用中,一个超低功耗的原型机瞄准了近距离(0.5到3米)检测。在学校、商场、交通枢纽和体育场馆等公共场所部署多个单位,将为随身携带的武器提供24小时监控。在第二个应用中,一个更高功率的原型将提供距离达15到20米的远距离检测。它的目的是为警察或安全专业人员提供便携式或可穿戴形式。**该系统通过分析雷达信号而不是图像来检测威胁。因此,不存在隐私问题。检测结果是一个警告信号,自动触发用户定义的响应(例如,拍摄场景的照片或消息安全)。我们的设备使用微波,它是非电离的,比手机的微波弱,确保公共安全。****
