摘要:
 随着长线列红外探测器技术的发展,其在空间遥感领域中得到愈来愈广的应用。亚像元探测技术在空间遥感领域已得到了广泛应用,在可见波段SOPT5卫星通过亚像元探测技术获得了2.5 m分辨率的高分辨率图像。给出了一套中波红外亚像元探测系统的设计方法。设计以交错排列的中波探测器为成像焦平面,设计了包括光学系统、杜瓦结构、基于PFGA的控制时序以及信号处理电路、采集系统以及图像显示的一整套系统。以该系统为终端,进行了目标成像试验,并对图像进行了非均匀性校正处理以及图像的重建。
Abstract:
With the development of long line array infrared detector, this technology gets more and more wide applications in the field of space remote sensing. Sub-pixel detection technology has been widely applied in the field of space remote sensing. By using the sub-pixel detection technology, SOPT5 satellite obtained high-resolution images of 2.5m resolution in the visible band. This paper produces a design of medium-wave infrared sub-pixel detection system. This design uses staggered MW detector as imaging focal place. Also, it includes the optical system, Dewar structure, timing control and signal processing circuit based on FPGA, acquisition system and image display. Using this whole system as the terminal, we do imaging experiments of the goal, and then deal with the non-uniformity correction and do image reconstruction.
