Abstract :
A wideband time-domain reflectometer has been used to evaluate the bistatic performance of the scattering coefficient of RF/microwave absorbers. The scattering coefficient has been measured inside an anechoic chamber in the 30-1000-MHz frequency range in the case of specular reflection. The scattering coefficient increases with incidence angle, and the measurement accuracy is ±2 dB
