Methods for Reflectivity Measurements of Objects and Materials on the Low Frequency

It is proposed a method for reflectivity measurements on the low frequency. Measurements on a frequency range between 0,2 to 1 GHz have been successfully accomplished. The results of measurements both in an anechoic chamber and in the GTEM-cells are also given. Regarding radio-absorbing materials it is proposed technique of using GTEM-cells. For reducing the noise the time domain processing is used.
