The classical and widely used termination -VSWR method, used to measure the reflectivity of an absorber wall in an anechoic chamber, has been recently upgraded. This measurement (slotted-line measurement type) was in the past realized frequency by frequency, with an amplitude transmitter/receiver and one antenna on a moving cart. It is now possible to cover a complete frequency bandwidth without any movement with the advanced VSWR method (A VS WR), and also with the RCS method. These two complementary methods do not require antenna movement, and allow measuring complete bandwidths at the same time, where only a few frequencies were measured before. It is not an exaggeration to say that the progress is as high as the transition between the slotted-line measurement technique and automated vector network analyzers at the end of the 1970s.

“…We have previously used the matrix pencil method in the frequency domain to correlate measurements in semi-anechoic and anechoic chambers at resonance-free frequency ranges [5]. It is complementary to the time-domain approaches that we have pursued previously [6]- [8]. In these measurements, the wide-band time-domain reflectometer was used to evaluate the bistatic performance of the scattering coefficients of RF/microwave absorbers.…”

A new method for evaluation of an anechoic chamber using the matrix pencil method is presented. A signal measured between two antennas placed in an anechoic chamber is sliced into small frequency intervals and is processed using the matrix pencil method. In each interval, the measured signal is decomposed into its propagating-wave components, which correspond to a direct propagation between two antennas and reflected propagating waves from absorbing walls. The ratio of amplitudes of the reflected wave components with respect to the direct path propagation gives a new measure of quality factor for an anechoic chamber.
