Orientation weighting restricts the direction of trajectories by predicted candidate trajectories and shrink ferret window , and reduces the amount of calculation . truncated sequential probability ratio test ( tsprt ) is also a algorithm of tbd , it can improve calculation efficiency by multistage thresholds to truncate tree - structured list of candidate trajectory of low degree of confidence 截断序贯似然比方法也是一种tbd检测的方法,其通过多级门限截断置信度较低的轨迹树达到提高效率的目的,在动态规划中加入该算法,使之积累的轨迹数减少,降低了计算量和存储量。
The sequential probability ratio test (SPRT) is a specific sequential hypothesis test, developed by Abraham Wald. Neyman and Pearson's 1933 result inspired Wald to reformulate it as a sequential analysis problem.
