Abstract

We describe the modeling of the backscattering of extended radar targets and discuss an experimental based method of determining the model parameters. These target models can be used in simulation and evaluation problems where we give some examples for a high resolution radar. In a large number of applications of these radars (frequency 94 GHz and higher), the resolution of the cell is smaller than the complete target. For MMW the backscattering of the illuminated section of that target is characterized by the interference of a `large amount' of scatterers. For the radar-cross-section (RCS) of the illuminated target section (so called `local' RCS), this results in such an extreme variation with respect to angle and frequency, that a deterministic description doesn't seem to be adequate. In these circumstances, our MMW-target-model provides spatial and aspect angle depending statistical data. As an example, the complete procedure is demonstrated with a 94 GHz FMCW-Radar with a 3-dB-beam of approx. 2 degree(s).
