The article discusses the characteristics of infrared background and small target in actual project application,an advanced max-median filter algorithm is proposed to improve SNR performance,and Robinson filter is used to suppresses background effectively.The two algorithms are implemented in FPGA in real time and save much time for other algorithms.The pretreated images are transmitted to PC by PCI bus.The experimental results show that the method can eliminate serious noise,and can suppress the background effectively.
