摘　　要：通过对线阵焦平面成像系统失效元产生及影响的分析 ,说明失效元补偿的意义 ;在借鉴国外技术的基础上 ,提出相应的自动检测及补偿方法 ,并通过计算机模拟对实际的热图像进行验证 ,结果证明该方法简洁可靠 。The affect and generation of Defective Pixels in Scanning IFPA Imaging system are analyzed and several Defect compensation ways are introduced based on the current technology abroad. A method of detectivity defective pixels is suggested and certified by computer simulation which can be carried out simply and effectively and realized easy by hardware. More than 2 compensated images were got.
