Track-before-detect Algorithm based on Cost-reference Particle Filter Bank for Weak Target Detection

no code implementations25 Sep 2023 Jin Lu, Guojie Peng, Weichuan Zhang, Changming Sun

This paper presents a track-before-detect (TBD) algorithm based on an improved particle filter, i. e. cost-reference particle filter bank (CRPFB), which turns the problem of target detection to the problem of two-layer hypothesis testing.
