Abstract
The characteristics of a system for video imaging of objects in the 3-mm-wavelength range are presented. A calculation procedure and characteristics of an aspherical single-lens objective that is used for imaging (point scattering function, resolution, and field of vision) are presented. An 8 × 8 array of antenna elements that are loaded with detectors is used for the detection of signals in the image plane. A digital processing unit is used for the detection, control, and input-output of electric signals that form the image. The processing and data-transfer rates of the unit are presented. Test experiments on imaging of simple objects (one or several metal spheres with different diameters) are performed in the active radar regime using the proposed system and monochromatic signal.
