High Dynamic Range Antenna and RF-Subsystem For FMCW Imaging Radar

摘要

Due to the inherent limitation of a FMCW radar in processing echo signals before the critical conversion to video frequency, it is necessary to adapt filtering characteristics of antennas and receiving circuitry as well as to employ high dynamic range frequency converters. As a result, imaging radar operation becomes possible under extreme RCS dynamic range with low spurious signal generation, i.e. good suppression of image artefacts.
