An Improved Dynamic Programming Based Track-Before-Detect Approach for Dim Target Detection

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 202)


In this chapter, the authors propose an improved dynamic programming (DP) based track-before-detect (TBD) to detect small targets in a high pulse repetition frequency (PRF) radar. Unlike most DP TBD methods in the literature which only use the accumulated energy to decide if a target is present, the proposed algorithm jointly process several low-threshold-crossing data frames, and uses both the accumulated energy and the frequency of being associated to decide if a target is present.
