Embodiment Construction

[0010] The infrared radiation calibration measuring system that embodiment adopts sees figure 1 . It consists of sounding balloon 1, blackbody target ball 2, infrared telescope tracking and detection vehicle 3, infrared detection data processing and blackbody measurement data receiving vehicle 4, etc.

[0011] The sounding balloon 1 uses a common 1000g latex balloon, which can carry the target ball to a height of more than 30 kilometers after being filled with helium. For the structure of the blackbody target ball, see figure 2 , is a hollow ball spliced ​​by 16 spherical bodies 5 with a thickness of 4 cm. The material of the spherical body is cut and shaped by polystyrene foam material, which can maintain a certain strength and reduce the weight of the black body ball. The two poles of the sphere are connected to a cylinder 6 made of the same material. The outer diameter of the ball is 1 meter, and the outside is covered with a jersey stitched with a layer of black nylon...

Abstract

The invention discloses a black body spherical surface temperature measurement system for external field infrared radiation measurement and correction. A tailor-made black body target ball which hangs under a common sounding balloon rises into the air at a certain raising speed. A plurality of temperature sensors are arranged on the surface of the black body target ball and are used for sounding the ball surface temperature and transmitting the measured data which is subjected to primary treatment of a microprocessor to the ground through a wireless data transmission module. A wireless data receiving module on the ground transmits the received data to a data processing computer, and the data processing computer processes the data so as to obtain an actual temperature of the target ball surface. The infrared radiation data of the target ball in a specific wave band can be acquired according to the target ball surface temperature, the infrared emitting ability and the projected area. The target ball is tracked and detected by an infrared telescope so as to acquire the infrared radiation data of the target ball. A correction parameter can be acquired by analyzing and comparing the two kinds of radiation data.

Description

technical field [0001] The invention provides a blackbody sphere surface temperature measurement system for external field infrared radiation measurement and calibration, and relates to the fields of infrared radiation measurement technology, GPS application technology, single-chip microcomputer application technology, digital communication technology and the like. Background technique [0002] Infrared radiation temperature measurement technology is widely used in non-contact measurement and target recognition of the surface temperature of the measured object. [0003] Infrared temperature measurement equipment is composed of optical system, photoelectric sensor, signal amplifier, data processor and display output. The optical system gathers the infrared radiation energy of the measured target in its field of view, and the size of the field of view is determined by the optical parts and their positions of the temperature measuring equipment. The infrared radiation energy o...
