摘要：

The demand on advanced personnel screening systems led to the development of several active and passive imagers. Among them, active multistatic imaging ensures high image quality and allows fully electronic screening. An active E-band imager is presented in this paper, which measures in real-time and delivers images of 30-dB dynamic range. Imaging of humans is achieved by optimizing the acquisition time using a dedicated digital signal processing solution. This paper introduces the system hardware, the calibration procedure, and several measurement results demonstrating high quality imaging capabilities.
