A simple measurement and data processing system is presented which, at the output, on a television screen, continuously and on line yields a one-dimensional radar image of rotating targets together with the corresponding two-dimensional optical image. The system makes use of the well-known fact that the fine structure in the instantaneous Doppler spectrum of the radar echo from a rotating target yields high cross range resolution of the scattering centers. It is very useful for the analysis of the scattering center distribution on complicated targets, for on line evaluation of the effect of comouflaging and for related areas as glint analysis and RCS prediction, for example.
