Method and apparatus for high-resolution image of test object by means of electromagnetic waves, in particular for controlling people to suspect objects

摘要

In order to image of test object by means of electromagnetic waves, in particular millimetric waves, the test object is illuminated with the electromagnetic waves, the scattered waves are received, and for a pictorial representation of the test object according to the principle of "synthetic aperture radar" (sar) evaluated.In order in a short period of time as large an area as possible with high resolution to be able to be imaged, according to the invention, the phase centers of the transmitter - and receiving antennas on a circular path parallel to the respective digital focal planes of the imaging system and at the same time moved in a further direction parallel to the respective focal plane displaced linearly.Preferably, the method for controlling people to suspect articles, for example, for the control of passengers on an airport, applied.
