Imaging Method: An Efficient Algorithm for Moving Target Tracking by UWB Radar

This paper presents the imaging method applied for moving target tracking by a multistatic ultra-wideband radar system. The imaging method consists of such signal processing phases as raw radar data pre-processing, background subtraction, the fusion of the data obtained by the particular receiving channels of a radar, detection, localization and the tracking itself. In this paper, the particular phases of the imaging method are described. Firstly, the theoretical base of the particular phases is denoted and then an overview of the signal processing methods which can be applied within corresponding phase is given. Here, we will also outline that a signal cross-talk, exponential averaging, 2D double-stage ( , ) N k detector, a target gravity center estimation and a low-complex nonlinear two-stage tracking filter can be used within the mentioned radar signal processing phases as convenient signal processing methods. The good performance of the imaging method presented in this contribution is illustrated by processing signals obtained by the ultra-wideband radar for a scenario represented by through wall tracking of a single moving target.
