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