The performance of IR sensors for target detection is analyzed with model SENSAT. The model calculates the radiometric relations for passive IR sensors with up to three homogeneous objects in the instantaneous field of view. For the atmospheric part, the computer code LOwTRAN-6 is used within SENSAT. The sensor model has been improved by introducing a noise model for quantum detectors. It takes into account photon noise, thermal detector/preamplifier noise, and g-r and 1/f noise. In combination with a spectral band optimization with respect to the SNR an efficient tool for the radiometric analysis of IR sensor performance is presented. The comparison of model calculations in the 3-5-micro and 8-14-microm bands with experimental measurements yields excellent agreement.
使用SENSAT模型分析了红外传感器用于目标检测的性能。该模型计算了瞬时视场内有多达三个均匀物体的被动红外传感器的辐射关系。对于大气部分，在SENSAT中使用了计算机代码LOWTRAN - 6。通过引入量子探测器的噪声模型对传感器模型进行了改进。它考虑了光子噪声、热探测器/前置放大器噪声以及g - r和1/f噪声。结合针对信噪比的光谱带优化，提出了一种用于红外传感器性能辐射分析的有效工具。在3 - 5微米和8 - 14微米波段的模型计算与实验测量结果的比较显示出极佳的一致性。
