Current SAR imaging techniques assume that radar pulses are reflected from a scene by a single bounce event (reflection from a sphere), or multiple bounces producing a fixed phase-centre (a trihedral). However, scattering is often more complex; e.g. the pulse may reflect off the ground before interacting with a vehicle, leading to additional bright returns in the image which are not located at the position of either bounce. In this paper we use simulation to assess the affect of multipath on vehicle signatures and develop techniques for the identification and removal of multipath returns from SAR imagery.
