A tracking approach based on Dynamic Programming Track-Before-Detect

Dynamic programming (DP) based track before detect (TBD) is an efficient algorithm to detect moving target with slow maneuvers when the SNR is low. After the integration process of DP algorithm, however, the track separation phenomenon is a prevalent problem for trajectory recovering. In this paper, a modified DP algorithm is used to process the data after the envelope detection of radar system. The track separation phenomenon is analyzed and also a tracking approach is presented to minimize the track separation. Simulations are made to show the good performance of this tracking approach.
