摘　　要：红外双波段成像探测器能接收目标和干扰源在两个波段上的辐射能量。从普朗克黑体辐射定律出发,根据MATLAB软件模拟出的目标和干扰源的辐射特性来选择SW/MW两个红外波段。首先利用仿真程序计算InSb面阵探测器对于点黑体和面黑体的响应结果,由计算结果和测试结果较好的一致性,说明设计的MATLAB仿真程序具有实用性。再从实际研制的HgCdTe 128×128叠层式双波段器件结构考虑,通过一定的变换,利用仿真程序对HgCdTe SW/MW双波段成像探测器进行参数性能仿真,达到利用成像及双色比来区分目标和干扰的目的。Dual band IR imaging detector can be responsive to two correlated spectrum of the target and the flare. Based on Planck＇s law of blackbody radiation, according to the radiation characteristic of the target and the flare simulated by MATLAB, the SWIR/MWIR band is chosed. First we calculate the response results of InSb IRFPA to the cavity blackbody and the extended area blackbody, because the simulated results are consistent with the tested results. The simulation procedure is of practical value. Then consideration of the HgCdTe 128 × 128 detector pixels are stacked, simulating the performance parameters of HgCdTe SW/MW dual band IR imaging detector with MATLAB procedures. The purpose of distinguishing the target from the flare with image and dual band ratio can be achieved.
