Abstract

The invention relates to a high vertical resolution 0-4km atmosphere temperature and humidity microwave detector, which comprises a drive control and data processing system. The drive control and data processing system is connected with a motor and a microwave fine spectrum system, the microwave fine spectrum system comprises a microwave fine spectrum receiver, the motor is connected with a plane mirror, a paraboloid is arranged between the plane mirror and a signal path of the microwave fine spectrum receiver, and a calibration body is arranged near the plane mirror. The invention designs a 0-4km temperature and humidity microwave detector with global observation capability, high precision and high vertical resolution. The instrument can realize adjustable, programmable, high-sensitivity and high-stability microwave fine spectrum detection, can obtain time-continuous, high-precision and high-spatial-resolution atmospheric boundary layer temperature and humidity profile information, and can be deployed on various air-based platforms such as airplanes and floating air balls; and necessary technical reserve is provided for arranging related instruments to space-based platforms such as space stations and satellites in the next step.

Description

technical field [0001] The invention relates to the field of principle design of microwave instruments, in particular to a high vertical resolution 0-4km atmospheric temperature and humidity microwave detector. Background technique [0002] After half a century of hard work, my country has successfully launched 17 meteorological satellites, 7 of which are currently in orbit, forming a comprehensive earth observation capability that takes into account imaging detection, covering visible infrared microwave and other spectrum bands, and has become the world's largest meteorological satellite with both polar orbit and One of the few countries that has stationary two series of operational meteorological satellites. my country's second-generation Fengyun meteorological satellite, Fengyun-3, is equipped with two atmospheric microwave detection instruments, including a microwave thermometer and a microwave hygrometer. As a remote sensing instrument independently produced in my count...

AI Technical Summary

Problems solved by technology

The temperature and humidity profile of the boundary layer is the key basic data, and traditional observation and ground-based remote sensing methods cannot achieve global observation

Although satellite remote sensing can provide spatially continuous boundary layer atmospheric temperature and humidity profile information, the boundary layer information in the total detection signal is a weak signal relative to the surface, and the extraction accuracy of atmospheric information is low
