Providing a deeper look beneath the surface is key function of product security and materials scanners [1]. Until recently, only ultrasonic X-ray systems made this possible [2]. Now, electromagnetic waves, which allow view through nonconducting materials, offer competitive alternative [3]. While examinations using methods are common, because required safety regulations, option relatively costly. Current optical sensor systems, on other hand, inexpensive, but they limited information about...
A portable multisensor frequency modulated continuous radar (FMCW) networked concept is presented for the localization of persons trapped in debris building collapse scenarios. 2-D algorithm evaluated a field test to demonstrate successful detection respiration micromovements.
The following paper describes the development of an autonomous and compact millimeter wave scanning measurement system (SAMMI - Stand Alone Millimeter Imager) which works in W-Band (CW@78GHz). SAMMI <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> was developed to demonstrate high potential usability region for material classification[1].
Millimetre wave sensors are capable of measuring the structure and composition as well detecting small variations thereof in a wide range dielectric materials, such plastics, dry goods foodstuffs. To produce an image that modern recognition algorithms can be applied on, resolution, i.e. pixel density, comparable to those optical cameras has realized. In this paper, we present rotating scanner system operates CW mode at 90 GHz allows for high density medium measurement object velocities using...
Millimeter wave imaging technologies offer a wide spectrum of new applications. Research results the last year's show, that millimeter waves can be used to detect letter bombs and non-metallic impurities inside products or control material parameters in real-time applications fluctuations during production. The main challenge for an operational system is development fast cheap scanner concepts this frequency range
