Paper Abstract

This paper investigates the variability of the human body radar signature, for both stationary targets (where we are interested in the radar cross section) and moving targets (where we are interested in the Doppler response). The approach in this paper introduces both mesh distortions and variable walking patterns, in order to predict changes in the radar signature induced by morphological changes in the human meshes. The study is based entirely on computer simulations. We start with a basic human mesh and use the Maya software package to articulate or distort the model. Realistic human motion animation is obtained by using spatial coordinates from real motion capture data. The radar signature is obtained by running a Finite Difference Time Domain-based electromagnetic solver. Results are presented as radar cross section for stationary targets or Doppler spectrograms for moving targets.
