Windowed transforms applied to scattering data gathered along an elevated track parallel to a scattering surface are shown to provide local plane wave spectra which can be backpropagated to synthesise distinct features of the scattering environment. The method is illustrated for plane wave scattering from a truncated array of pitched strips.
