A TBD algorithm based on dynamic-programming for dim radar target detection
Xue Wang, Wanjie Song, Zijing Zhang, Zhu Hanmei · 2010
When the received echo signal energy reflected from a target is quite small, the target cannot be detected reliably with traditional accumulation and detection method. In this paper, based on the stable factor, an improved method is proposed, which utilizes the difference of correlation characteristics between clutter and target to suppress clutter spike. Then the track-before-detect algorithm based on dynamic-programming is applied to dim radar target detection. Compared with the combination method of coherent and non-coherent integration, the predominance of the algorithm is obtained on dim radar target detection.
