This invention provides a dual-platform absorbing tip transverse positioning system, installed on the floor of an anechoic chamber to simulate different radio wave environments. The system consists of two parallel hydraulic platforms with densely arranged absorbing tips on them, and a raised floor is mounted on the hydraulic platforms. The hydraulic platforms are driven by hydraulic cylinders to lift and lower scissor supports. Sprockets are located at both ends of the platforms, driven by chains, and a transverse motor is also provided. The motor drives the sprockets through gear engagement, causing the absorbing tips on the platforms to move laterally. The raised floor, originally a metal reference surface, can be adjusted to a non-reflective environment according to testing requirements. The hydraulic platforms rise, driven by the transverse motor, and the absorbing tips of the two platforms unfold laterally, providing a non-reflective test. The aforementioned actions are reversed, causing the platforms filled with absorbing tips to retract and disappear under the raised floor. This system can flexibly switch between different testing environment conditions to meet the diverse needs of the anechoic chamber.
