摘　　要：以Sofradir公司的红外中波320×256和长波288×4碲镉汞探测器为研究对象,建立了中波/长波红外碲镉汞焦平面探测器响应模型.对黑体温度响应特性曲线进行建模计算,并将计算曲线与常温段实测数据对比分析,结果显示两者具有较好的一致性,表明模型有效.从测试结果与模拟结果的一致性可以推测:响应模型对焦平面探测器探测低温目标具有参考价值.Taking Sofradir 320×256 MW and 288×4 LW IR detectors as study objects was established a response model of MW/LW IR HgCdTe focal plane detector and calculated response characteristic curves of black body.Comparing the calculated curve of model with the test response of real detector output,at normal temperature range,it showed good agreement and indicated fine effect of the model.The model could provide meaningful reference for target detection with low temperature by FPA detector,in terms of the coherence between test results and simulative ones.
