摘　　要：】考虑凝视热成象系统的工作特点，提出一种适用于该类热象仪ＭＲＴＤ预测的改进方法。该方法考虑了凝视焦平面探测器阵列的二维空间采样对热成象系统ＭＲＴＤ的影响，引进判据系数的概念，并通过离散傅里叶级数求之，使得凝视热成象系统ＭＲＴＤ预测结果与实验值较好地吻合。According to the characteristics of the staring thermal imaging systems, a improvement on MRTD prediction which is suitable for this kind of thermal imaging system is introduced .By this DFT coefficient, the space sampling effect and the phase effect can be embodied. The prediction results and experimental values are in good consistent.
