Research on the Measurement of Shipborne Infrared Radiation Characteristics Based on Low-temperature Blackbody

The demand and accuracy requirement for infrared radiation measurement system are increased with the development of technology and military weapons. The measurement accuracy is an important index of the infrared radiation system, in order to improve the accuracy of the system, it is urgent to carry out the research on the key technologies such as automatic supplantation control, radiation and automatic calibration, atmospheric transmission correction model and parameter inversion. In this paper, considering the presence of sea surface clutter, surface light and clouds, the basic principle of infrared radiation characteristic measurement and the composition of system construction as well as the influence factors of infrared radiation characteristics are demonstrated, and the precision verification of a certain infrared radiation characteristic measurement system is completed by means of the test design. The work presented in this paper is in favour of guiding the design optimization, fusion construction and device function expansion of optical system and structure in the future.
