摘　　要：在光电探测系统中,需要对小目标进行亚像素定位,提高跟踪精度。基于模型的亚像素定位算法,根据光学系统建立目标模型,然后采用牛顿迭代法计算使得模型能量最大的点作为目标的定位点,仿真结果表明,基于模型的小目标亚像素定位算法定位精度高,稳定性好等特点。Subpixel location is adopted to locate the small target to improve tracking precision in optic-electric detection system.After target model is set up based on optics system,Newton＇s Iterative Method is adopted to compute the point that make the model energy most,then the point is the location of the target.The simulation results show that the location algorithm based on model for small target can improve location precision and stability.
