Paper Abstract

Dual-band IR imaging detector can be responsive to two correlated spectrum of the target and the flare. With the equivalent temperature of the target and the flare, the radiation characteristic of the target and the flare is simulated by MATLAB which is based on Plank's law of the blackbody radiation, and the SWIR/MWIR spectrum is chose where the IR radiation is the largest difference between the target and the flare. The theoretical calculation procedure is designed according to the transform flow of the IR radiation. First we calculate the responsive results of InSb IRFPA to the cavity blackbody and the extended area blackbody, because of the simulated results are consistent with the tested results, the simulation procedure is of practical .Then consideration of the HgCdTe 128×128 detector with pixels are stacked, the performance parameters of HgCdTe SW/MW dual-band IR imaging detector are simulated with MATLAB procedures, the purpose of distinguish the target from the flare with image and dual-band ratio can be reached, and the two benefit conclusions can be achieved.
