Investigations toward micro-Doppler effect in digital broadcasting based passive radar

This paper proposes a passive bistatic radar (PBR) configuration using digital broadcasting as an illuminator for micro-Doppler effect experiments. First, the problems caused by a typical PBR usage scenario are introduced and the corresponding signal processing techniques are presented. Then, passive radar demonstrator and the experiments are described. Last, typical experimental results are illustrated and analyzed, which indicates the potential of PBR systems to detect target´s micro-Doppler signature and measure their characteristic parameters.
