Abstract:
A key problem in detecting and tracking weak targets is starving for being resolved in the field of radar signal processing. A method using coherent integration incorporated with trackbeforedetection approach based on dynamic programming algorithm is proposed for radar weak target detection and tracking. An idea of weighted direction is introduced to decrease the range of energy diffusion in dynamic programming algorithm. A technique of twostep detection thresholds is adopted to reduce the amount of computation. The results from both synthetic and experimental data show that the detection performance of this approach is better than the one of the traditional methods. It can be realized effectively that the detection and tracking of targets in low signal noise ratio. Furthermore, it has a higher speed of operation and is in more favor of project applications.
