Embodiment Construction
[0036] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0037] In order to solve the above technical problems, the present invention provides a detector non-uniformity degradation repair method, which improves the multi-integration time multi-segment two-point correction method, removes the influence of the detector response drift on the correction parameters, and solves the problem of detector degradation problem, including the following steps:
[0038] Step 1: Generate correction parameters;
[0039] Step 101: Calculate the fixed response offset of the detector;
[0040] Set N integration times I 1 , I 2 ,..., I N , collect M blackbody temperatures T 1 , T 2 ,...,T M The detector response data are D 11 、D 12 …D 1N …D MN ; where D 11 is the integration time for I...
