EXPERIMENTAL INVESTIGATIONS OF RADIO-ABSORBING COATINGS OVER A VERY BROAD FREQUENCY BAND

摘要

A radar measuring system which enables the modulus of the reflection coefficient of radio-absorbing coatings to be determined over a very broad frequency band (2―18 GHz) is described and the systematic features of the measurements are pointed out. The results are presented of a comparison of the frequency dependence of the power reflection coefficient of the coating, measured using the system described, with data obtained using narrow-band panoramic measuring equipment.
