Paper Abstract

A three band infrared integrated radiometer was developed for field measurement. The composition and work theory of the radiometer are described in this paper. The detailed calibration methods are analyzed for extended source and point source, and corresponding measurement results are given. With test data, the experimental results and instrument performance are analyzed in detail, in respect of the equivalent temperature of inter reference blackbody, linearity with target temperature, measurement error of point source and extended source. To lessen the influents of calibration for measurement, the attentive problems in actual calibration of extended source and point source are summarized, and satisfied results are acquired.
