基于图像序列的四元红外导引头信号源设计

摘要

For the requirement in development and test of infrared seeker, a signal source for quaternary IR seeker based on image sequence has been designed, which can make use of IR image sequence generated by software and flying data of other models and real-time output four pulse signals to the electronic cabin by hardware platform. The research is focused on signal source hardware system design based on PCI9054 and FPGA and wave generation method when image pixels and detector array are partly overlapped and the roll angle is not zero. The signal source designed can guarantees real-time and high accuracy.%针对红外导引头生产和研发的需要，提出了一种基于图像序列的四元红外导引头信号源设计方法，该方法可利用软件生成的红外图像序列和其它型号的挂飞图像，并由硬件平台实时输出四路脉冲信号给电子舱。重点研究了探测器阵列与图像像素部分重叠以及存在滚转角情况下探测臂波形的生成、基于PCI9054和FPGA的信号源硬件系统设计。
