In the radar targets detection and tracking process,because the target echo is a weak and typical small target,the detection algorithm routine is difficult to work well.After we defined the problem by making a long accumulation of small target detection radars and with the signal specificity,we propose the track-before-detect(TBD) scheme.In this paper,the target prediction is carried on firstly,and then the targets are tracked in this foundation.With the features of target movement along the various possible trajectories of energy accumulation,we make test to determine energy accumulation value,then detect the true target and extract the target trajectory.In the paper,the algorithm of dynamic programming applied to small target detection is description firstly,then the performance of this method is carried out a detailed analysis,and detection probability and false alarm probability expression is conducted a more detailed derivation.At last,threshold and the relationship between the probability of false alarm is come out by simulation and performance analysis.
