摘　　要：针对红外成像观测系统中获取的低信噪比、背景及噪声干扰严重的小目标图像的特点,设 计一种具有保护带(5×5 G)的5×5 Robinson空间滤波器,采用TMS320VC5402进行硬件实现。实验表明,该空间滤波器能够大大提高目标的信噪比,抑制背景和噪声,保证系统实时性要求,很适用于小目标检测。When small target images are acquired by an infrared imaging and observation system in the environment of low signal-to-noise ratio and severely disturbed by background noise, a designed 55 Robinson spatial filter with guard band (55G) is implemented by means of TMS320VC5402 hardware. The experiments show that the spatial filter can greatly improve signal-to-noise ratio, inhibit background noise and ensure the real-time requirements of the system. It is suitable for small targets detection.
