摘要
文中提出用截断序贯似然比检测、多级假设检验及航迹点信号强度滤波相融合的算法实现序列图像中低信噪比点目标的检测与跟踪，其中，点目标的位置、速度及运动方向均未知．文中推导了相应的序贯似然比判决准则及虚假航迹终结准则，并对该算法进行了详细的描述及仿真，仿真结果表明该算法可快速实现信噪比为２
A new algorithm is proposed for tracking low observable point source targets with an unknown position and an unknown velocity in a digital image sequence. It combines truncated sequential probability ratio test, multistage hypothesis tracking and intensity filtering to track moving point targets computation efficiently with a very low SNR. The simulation results show that it can detect and track targets with an SNR smaller than 2.
