✦ Synopsis

Radar cross-section measurement techniques in a relatively small anechoic chamber are discussed in this paper. The proper configuration of the measurement system and antenna/target setting for securing a wide dynamic measurement range is studied. A quasi-monostatic configuration is recommended here instead of a monostatic one, and various suggestions are made for reducing isolation error and background noise, along with calibration techniques and antenna settings. Measurement examples are shown for a conducting plate and parallel plane waveguide cavities. These results are then compared with those derived theoretically by the geometrical theory of diffraction and the WienerHopf technique. Good agreement is obtained between them, and the validity of our measurements is confirmed.
