What is a millimeter wave electromagnetic wave; usually the 30-300GHz frequency domain (wavelength 1-10 mm) electromagnetic wave is called millimeter wave, which is located in the overlapping wavelength range of microwave and far-infrared wave, so it has the characteristics of both spectrum. The 76-81GHz band of this product is the area with the least understanding and application development of human beings so far.

it realizes a tighter radio frequency architecture and a higher signal-to-noise ratio. 5GHz working bandwidth,:so that the product has higher measurement resolution and measurement accuracy. Coherence: Dipole oscillation driven by dry current or non-linear difference frequency effect of coherent laser pulse; Low energy: The millimeter-wave photon energy is only a few millielectron volts, and there will be no X-ray ionization and damage to the substance to be detected, so it is not easy to damage the substance to be detected. Strong penetrability: It has strong penetrating power for non-polar materials. Many non-metal non polar materials have less absorption of rays in this band, so they can be used to detect the internal structure of materials.For example,ceramics/cardboard/plastic products/foams are transparent to electromagnetic radiation in this band, and can also be used for airport/station safety monitoring, such as detecting machinery/explosives and drugs, or for circuit board welding detection. Easily absorbed by polar molecules: this band has less scattering in non-uniform materials, and can detect and measure water vapor content. It is also possible to study the material composition or carry out quality control by analyzing their characteristic spectrum. arge range and small blind area. The maximum range can reach 120m, and the blind zone can reach 8cm. Small beam angle and small antenna size make it easy to install. It is less affected by the size of the tank body and the interference of obstacles. The wavelength is shorter, and it has better reflection characteristics on the solid surface, so no special universal flange is needed for aiming. Support remote debugging and remote upgrade to facilitate the maintenance work of on-site personnel and liquid level measurement. It has the incomparable advantages of other ordinary microwave pulse radars and guided wave radars. The extremely narrow beam and penetrating ability are more effective. Adaptto ultra-complex working conditions without compromising measurement performance.
