FIELD: aerial engineering.
SUBSTANCE: cavity of radio-transparent envelope which has to be model of tested object is partially filled with electrically conducting liquid. Level of liquid is controlled by piston pump and measured by level meter. Radio-transparent cavity has a shape of circular cylinder with preset sizes which shape allows reproduce "selection" of standard reflectors in form of circular cylinders at smooth change in level of electrically conducting liquid. Values of dissipation effective areas of the cylinders can be calculated with high precision. Radio-transparent envelope can have shape of cylindrical pipe.
EFFECT: simplified process of test calibration; widened range of measured values of dissipation effective area.
