![]() ![]() The millimeter wave frequency of the atmosphere can achieve large-capacity satellite-ground communication or ground relay communication. ![]() To this end, they have significant significance in communication, radar, guidance, remote sensing technology, radio astronomy, and spectral. When the millimeter wave is propagated in the atmosphere during the atmosphere, some attenuation caused by gas molecular resonance is a very small frequency. Millimeter waves are smaller when they use the atmospheric window to spread, which has little affected on natural light and thermal radiation sources. The propagation attenuation in the atmosphere is severe, and the device processing accuracy requirement is high. Car radar is the main driving force of this wave of growth, but the Internet of Things market will become another wheel that drives the millimeter wave radar market. Marketsand Markets recently released data show that by 2023, the total market in millimeter Pod Sensors will reach $ 20.6 billion. However, with the development of the market, the scope of application of millimeter wave radar is outside the vehicle field, gradually expanding to smart cities, building automation, health monitoring, and other industries. It is now widely used in the ADAS (Advanced Driving Assistant System) in the automatic driving area. As a non-contact sensor, the millimeter wave radar has the advantages of accurate sensing, no interference. ![]()
