| Abstract: | 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 Wiener-Hopf technique. Good agreement is obtained between them, and the validity of our measurements is confirmed. © 1998 Scripta Technica, Electr Eng Jpn, 123(1): 8–14, 1998 |
