AI Technical Summary

Technical Problem

Existing infrared flight testing methods struggle to accurately correct for the effects of atmospheric radiation and environmental reflected radiation during high-altitude flight, resulting in insufficient measurement accuracy of the infrared radiation characteristics of ground targets and field sites, and also incurring high costs.

Method used

A two-stage calibration method is adopted. First, the calibration target cloth is calibrated at low altitude using a high-precision calibration body. Then, at high altitude, the ground target and the background of the position are calibrated using a large-area calibration target cloth. By calculating the entrance pupil and body radiance of the blackbody, gold plate, and calibration target cloth, the atmospheric environmental radiation and target radiation characteristics are obtained.

Benefits of technology

It enables accurate acquisition of the infrared radiation characteristics of ground targets and the background of the position during high-altitude flight, reduces testing costs, and provides data support for ground target tracking and identification.

Abstract

The application discloses an infrared hanging test calibration method, which adopts two-stage calibration, calibrates a large-area calibration target cloth through a high-precision calibration body at a first test height, and then calibrates the infrared radiation characteristics of a ground target and a position background by using the large-area calibration target cloth at a second test height. The infrared hanging test calibration method can not only accurately obtain the body radiation characteristics of the ground target and the position background in high-altitude test, and provide data support for ground target tracking and identification, but also can significantly reduce the test cost.
