Space-borne microwave atmospheric sounding instrument

Abstract

The invention relates to a space-borne microwave atmospheric sounding instrument, which comprises feed sources, calibration bodies, a motor, plane mirrors, parabolic reflectors, a scanning drive control module, multiplexers and receiver units. The motor is controlled by the scanning drive control module to drive the plane mirror to rotate. The plane mirrors reflect received electromagnetic wave signals to the parabolic reflectors in the form of plane waves by scanning the atmosphere and the calibration bodies. The parabolic reflectors realize secondary reflection to enable the plane waves to be reflected to the corresponding feed sources arranged opposite thereto. The multiplexers are used for separating the frequency of the electromagnetic wave signals received by the feed sources respectively. Each receiver unit comprises a plurality of receivers parallel with the output end of the corresponding multiplexer, and is used for receiving the electromagnetic wave signals matched with the frequency thereof. The space-borne microwave atmospheric sounding instrument has the advantages of being high in performance, high in integration, low in weight and low in power consumption.

AI Technical Summary

Benefits of technology

This invention relies about an improved wireless communication device called GNSS (Global Navigation Satellite System). It uses two types of radios: primary and secondary ones. These radios work together with each other to improve their performance. They use different frequencies from both signals while transmitting them through space without being affected by external factors like weather conditions. By combining these techniques into a single design, this improves overall functionality and efficiency compared to traditional methods.

Problems solved by technology

This patents describes two technical problem addressed in this patented technology: (1) how accurately measure air quality (temperature) during different stages of an outdoor activity like construction work without interferring with other activities on that area's surface due to their location and orientation within the environment being monitored. (2) How effectively separate high altitude cold temperatures from low levels caused by wind speeds when there may also cause clouds/rain pollution near areas where they should stay open.
