AUTOMATIC DETECTION OF OBJECTS WITH MULTISTATIC MILLIMETER WAVE IMAGING TECHNOLOGY

摘要

The Quick Personnel Security Scanner R&SQPS100 and R&SQPS200 deliver advanced imaging solutions for personnel screening at airports and other critical infrastructures. The fully electronic system acquires high-resolution complex three-dimensional imaging data with planar multistatic sparse arrays. Privacy of personnel is protected by analyzing imaging data automatically with the dedicated threat detection software, without storing or displaying raw image data. Potential threat objects are indicated to the end-user on an abstract avatar. The detection software must fulfill challenging requirements in terms of detection capabilities. A multitude of possible threats scenarios must be recognized with low false alarm rates, in order to provide the necessary throughput. For this purpose, an image processing and machine learning framework was developed for threat detection, which classifies image regions into normal or suspicious.
