Implementation of the Algorithm for Detecting Weak Targets at Complex Background by FPGA

从强杂波背景中检测目标是红外成像制导中的重要课题。数字信号处理器常常因为在复杂性、运算速度等方面的限制,难以实时实现复杂的检测方法。本文针对红外点目标检测的要求,给出了用现场可编程门阵列(FPGA)实现复杂背景下点目标检测算法的方案。实验结果表明,本文设计的方案能有效检测出红外弱小目标,为后续处理节省更多的时间,具有实际应用价值。

It is an important task to detect the weak targets in IR images with complex backgrounds. Digital signal processing system can't implement complex detecting algorithms in real time because of the limitations in the complexity and operation speed of system. In this paper, we present an infrared signal processor platform which can implement the algorithm for detecting the weak and small targets by FPGA. The platform can implement the algorithm in real time. The result of experiment has indicated that the way is valuable to detect and track the weak and small targets.
