Abstract

The HUT Radio Laboratory develops a novel compact radar cross section (RCS) test range for scale model measurements. The test range is based on a phase hologram that converts the feed horn radiation to a plane wave. The measurements are performed using CW at 310 GHz in a quasi-monostatic radar configuration where the identical receiving and transmitting corrugated horn antennas are placed side by side. The feasibility of the phase hologram RCS range has been verified with simple test objects such as a metal sphere and a small metal plate. The work continues toward a monostatic radar configuration.
