Description

technical field [0001] The invention relates to the technical field of microwave testing equipment, in particular to a high-temperature-resistant detection device for microwave-absorbing composite materials. Background technique [0002] Radar absorbing materials (referred to as absorbing materials) are widely used in civil and military fields, and radar reflectivity (referred to as reflectivity) is an important index parameter used to evaluate the absorbing performance of absorbing materials. The reflectivity measurement technology of absorbing materials at room temperature is relatively mature and has been widely used. However, as engines, high-speed aircraft and high-power microwave devices increase the temperature resistance of absorbing materials, radar The requirements of the reflectivity test system are also getting higher and higher. [0003] At present, the high-temperature reflectivity test system mainly adopts the method of bottom heating, that is, the heating el...

AI Technical Summary

Problems solved by technology

[0003] At present, the high-temperature reflectivity test system mainly adopts the method of bottom heating, that is, the heating element is arranged under the sample to be tested, and the radar wave incident surface is the upper surface. When testing the high-temperature reflectivity of the sample to be tested, the hot surface and the radar wave incident surface are not On the same side, it is inconvenient to adjust the heating angle, and it is impossible to carry out heat preservation and transfer work during the heating process, resulting in a large amount of heat loss, which cannot meet the needs of use
