FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering, namely, to anechoic chambers (AC) designs, intended for radar targets effective reflective areas (ERA) diagrams measuring. Anechoic chamber, made in enclosed room, in which inner walls, floor and ceiling are lined with radar absorbing material, wherein room longitudinal cross-section is made in form of trapezium with horizontal base. At that, room rear end wall is installed at angle β=(90°-arc tg√ε), where ε is radar absorbent facing material dielectric permittivity.
EFFECT: technical result consists in elimination of radio waves mirror reflection from AC rear end wall.
