摘　　要：针对海空背景红外图像中弱小目标的特点,结合自主设计的以TMS320DM642 DSP芯片为主处理器的硬件处理平台的资源性征,设计了两种适合硬件处理平台实现的单帧目标提取算法。实验证明该算法检测效率高,实时性好。Based on the characteristic of dim infrared point target in sea-sky background and the peculiarity of hardware processing plat taking TMS320DM642 chip as CPU, two dim point-targets detect algorithms which can be implemented easily on the hardware processing plat are presented. The results show that the dim point-targets can be detected accurately, and its detectability real-time operability is good.
