Anechoic Chamber & Shielding Room
Main application areas
In the military field: It is widely applied in the stealth performance testing of fighter jets, missiles, radars and other weapons and equipment, as well as electronic warfare confrontation testing, etc. It is a key link in ensuring the reliability of equipment.
In the civilian field: Civilian products such as automotive electronics, communication equipment, and medical equipment need to pass microwave anechoic chamber tests before mass production to ensure electromagnetic compatibility and performance stability.
Key Parameters
1. Core composition
Shielding housing: Constructed with highly conductive materials (such as cold-rolled steel plates, copper plates), it forms a closed space to prevent external electromagnetic signals from entering and at the same time prevent internal signal leakage. The shielding efficiency can reach 60dB-120dB.
Absorbing materials: The interior walls, ceilings and floors of the anechoic chamber are covered with absorbing materials such as conical carbon-containing sponge absorbing materials or ferrite sheets, which absorb electromagnetic wave energy, reduce reflection, and bring the electromagnetic environment inside the anechoic chamber close to an "ideal vacuum" state.
2. Main functions
Electromagnetic compatibility (EMC) testing: Detect the electromagnetic radiation intensity of the equipment during operation (EMI testing) and anti-interference capability (EMS) testing: Ensure the normal operation of the equipment in complex electromagnetic environments.
Antenna characteristic testing: Measure parameters such as antenna gain, pattern, and impedance matching to provide data support for antenna design optimization.
Radar cross-sectional area (RCS) testing: It is used to evaluate the stealth performance of aircraft, tanks and other equipment. By measuring the radar echoes of the target with radars of different bands, the radar reflection cross-sectional area is accurately calculated.
3. Key parameters
Overall Dimensions: 69.0m×39.0m×32.0m (L×W×H)
Shielding Door: 15.0m×10.0m, load capacity 10t, fully automatic sliding door
Shielding Design: Large-panel pre-assembled welded shielding; panel size 1.25m×9.0m
Top Installation: One 20t overhead crane and one 5t overhead crane; automatic opening/closing system for absorbing materials
4. Technical features
Large size and high precision: Large microwave anechoic chambers can accommodate full-sized aircraft, tanks and other large equipment. They have extremely high requirements for absorbing materials and shielding technology, and must ensure the absorption and shielding effects in high-frequency bands (such as millimeter waves and terahertz waves).
Intelligence and Automation: Modern microwave anechoic chambers are equipped with intelligent testing systems, enabling automatic parameter setting, real-time data collection and analysis, and enhancing testing efficiency and accuracy.
