Ship-borne Radiation Measuring System United Calibration Based On Environment Temperature Self-adaption Amendment

As an important component informatization database, infrared data has been extensive used territories such as night investigation, weapon navigation and long-range early warning, etc. Ship-borne infrared radiation characteristic measuring system works in the marine environment, the variation of temperature and humidity is huge. In view of the variation of environment’s temperature affects bias a lot but gain for the measuring system, this paper presents an united calibration method internally and externally based on environment temperature self-adaption amendment and amend temperature influence by means of self-adaption interpolation, thus accomplishes the valid measuring system assessment for sensibility and responsive characteristic of external target. Radiant calibration in different infrared waveband has completed by the measuring system, serial temperature have been set in each integrating time to calibrate and fit, and determined the effectiveness of the method by error statistics. In the meanwhile, the radiant characteristic of high-precision black-body and aquatic target are inversed. As a result, the obtained minimum error of 6.82%, the maximum error of 10.21% for black-body measuring precision and high confidence coefficient for measured radiant inversion value verify the effectiveness and application prospect of the calibration method presented in this paper, ulteriorly.
