FIELD: physics; radio.
SUBSTANCE: invention relates to radio engineering and may be used to measure radar cross-section diagrams for radar target simulators. Anechoic chamber is a room with walls, floor and ceiling covered inside with radar absorbent material sheets. Anechoic chamber transverse section is a parallelogram, two sides of which form acute angle ϕ with vertical plane, and the other two with the horizontal one. Anechoic chamber longitudinal section is a horizontal-base trapezoid. ϕ angles are equal to ratio of anechoic zone diameter D to four distances from anechoic zone outer surface to the closest inner surface of anechoic chamber L or exceed this value (ϕ≥D/4L).
EFFECT: reduced diagram measurement error and reduced chamber cost.
