METHOD OF MEASURING REFLECTION CHARACTERISTICS OF ECHO-FREE CHAMBER AND DEVICE FOR EFFECTING THE SAME

摘要

Using; microwave equipment, namely methods of measuring the reflective characteristics of anechoic chambers (BEC). The aim of the invention is to determine the ability of BEC reflectance in the test direction. SUMMARY OF THE INVENTION: radiate radio waves in the direction of the working volume of the chamber by an antenna. Iz4 working volume of the energy re-emit waves in the test direction BEC wall, reflected waves from the wall back into the working volume perootrazhayut towards the receiving antenna. Part of the wave energy from the working volume BEC pereotrazhayut also towards the antenna. Alter the phase of the waves scattered nnyh BEC wall portion within at least GCR. At the output of the antenna was measured maximum and minimum power values ​​of the received signals and determining the echo ratio or reflectivity BEC in the test direction using the formula. In this case the reflector is in the form of two parallel rectangles dimensions a x b x and the distance between them is 2r, and the reference scatterer made of two half-cylinders of radius r and length hydrochloric "a, each of which is connected to the first rectangle storone.Hkazhdo- and surface semicylinders conjugated to the planes of the rectangles on the compound line. 2 yl.
