    With the appearance of hypersonic weapon, it is a coming tendency to measure radiation in wide dynamic range from low temperature to high temperature. At present, the research of wide dynamic range radiometric measurement is relatively few. In this paper, a dual correction of collimators and attenuators method was proposed for wide dynamic radiation measurement to further improve the accuracy of high temperature infrared radiation measurement. The experiment was carried out based on the mid-wave infrared radiation measurement system of 600 mm aperture. The radiation measurement results with attenuators 2%, 10% and 20% were corrected, and the original measurement accuracy was increased by 3.31%, 3.27%, 1.60% respectively. It is proved that the correction method can effectively improve the accuracy of radiation measurement, which has certain engineering practice significance.
