Track-Before-Detect Method Based on Preprocessing with Pseudo-Spectrum

Traditional dynamic programming based track-before-detect (DP- TBD) methods may suffer performance loss due to the suboptimal preprocessing. In this paper, a DP-TBD method based on preprocessing with pseudo-spectrum is proposed. For each cell in the observed image, a pseudo-spectrum is constructed around the cell itself with measurement value as its peak according to a point spread function. Samples of the pseudo-spectrum are added onto …
