提出了一种针对手枪、刀具等隐蔽导电物品的主动对峙检测与识别技术。这种技术需要用宽范围阶跃毫米波辐射照射物体，并诱导由模式叠加组成的局部电磁场。从照明和散射场到这些模式的耦合通常是频率相关的，这构成了检测和识别导电物体的基础。如果要激发和收集全光谱的模式，从而获得全频率响应，则物体需要被充分照亮。散射电磁功率是在几米的“距离”处测量的，因为照明场被扫频，并寻找目标物品的频率响应特性模式。该系统依赖于baum1所采用的面向无关的延迟响应的贡献，以及来自炮管的面向无关信息和散射效应的偏振。该技术适用于可展开的火炮和隐蔽武器探测系统，不依赖于成像技术来确定火炮的存在。典型金属或部分导电物体（如钥匙、移动电话和隐藏的手枪）的反应实验集在一定频率范围内呈现。
An active technique for the standoff detection and identification of concealed conducting items such as handguns and knives is presented. This technique entails illuminating an object with wide range stepped millimetre wave radiation and inducing a local electromagnetic field comprised of a superposition of modes. The coupling to these modes from the illuminating and scattered fields is, in general, frequency dependent and this forms the basis for the detection and identification of conducting items. The object needs to be fully illuminated if a full spectrum of modes and therefore a full frequency response are to be excited and collected. The scattered EM power is measured at "stand off" distance of several metres as the illuminating field is frequency swept and patterns in frequency response characteristic to the target item being sought are looked for. This system relies on contributions from the aspect independent late time responses employed by Baum1together with aspect independent information derived specifically from gun barrels and polarisation from scattering effects. This technique is suitable for a deployable gun and concealed weapons detection system and does not rely on imaging techniques for determining the presence of a gun. Experimental sets of responses from typical metal or partially conducting objects such as keys, mobile phones and concealed handguns are presented at a range of frequencies.
