Comparison of Modelled to Measured High-Resolution ISAR Data
other
We have obtained modelled ISAR data for a ZSU-23-4 air defence unit using a high-fidelity 600,000 facet model and the RAPPORT RCS prediction code. These ISAR data are compared with results from the FERMAT RCS prediction code using the same facet model of the ZSU23-4. In order to analyse how well the prediction results can represent measured ISAR data the modelled data are compared with measured ARL ISAR data of a ZSU-23-4 where the same parameters and resolution have been used. In addition we compare the modelled data with measured ISAR data from other targets than the ZSU-23-4 in order to check whether the measured and modelled data of the same target are more similar compared to data from other targets. We found that modelled and measured data certainly have common characteristics but that they are not similar enough to replace measured by modelled data for the purpose of target discrimination.
