摘　　要：在室内和室外环境下,W波段的辐射计能够有效地检测隐匿在厚外衣下面的金属和非金属武器。针对隐匿武器检测问题,在毫米波辐射计的理论基础上,开发了一种基于USB2.0接口的3 mm波便携式辐射计数据采集与测试系统。并给出了详细的硬件设计方案,实现了所有数据的自动采集、传输、测试和显示。最后通过实验验证了该方案是可行的,实现了隐匿武器检测系统的小型化和便携化。W-band radiometers can detect metallic and non-metallic weapons concealed under heavy garments effectively in both indoor and outdoor situations.To detect the canceled weapons,a kind of portable data collection and measurement system for 3 millimeter wave radiometer was developed on the basis of USB2.0 peripheral controller,based on the millimeter wave radiometer theory. The hardware design scheme was described in detail.All data acquisition,transmission,measurement and display were realized automatically.Experimental results show that the scheme presented is feasible,and the miniature and portable system of canceled weapons detection is realized.
