Abstract：In view of detection and tracking issue with large phased array radar for near-space hypersonic targets, a Modified Triple-Stage Hough Transform (MTS-HT) Track-Before-Detect (TBD) algorithm is proposed. Firstly, in order to reduce huge computational load problem from direct three-dimensional Hough transform, three- dimensional measurement points are mapped into range-time plane, azimuth-time plane and elevation-time plane in turn for two-dimensional Hough transforms. Besides, to decrease the impact from strong interference, meanwhile, make full use of energy information of points, point selection is carried on by double integration means of non-coherent integration and binary integration in every stage. Finally, false trajectory will be reduced effectively by motion constraints as well as merging of similar trajectories and the final trajectory from sequence association can be obtained. Simulation results show that proposed algorithm can realize effective detection and tracking for near-space hypersonic targets with relatively high trajectory detection probability and low false trajectory detection probability.
