Simulations supporting the design of a measurement model of an unmanned aerial vehicle with low radar signature

Kurzfassung

The objective of the NATO/STO/SET-252 Task Group is to design and manufacture a validation model of a representative target in terms of geometrical complexity and the use of material s for the reduction of main scattering mechanisms. Computational Electromagnetics (CEM) is a crucial engineering tool in the overall design process and used to identify the scattering centers, to assess the effect of coatings or distortions like surface roughness, and finally to ascertain the radar signature of the model. Cross-comparisons of computational results are performed using different formulations and methods. With regards to the future growing number of autonomous and unmanned vehicles and services, the results are not only military relevant but also valuable for civil air traffic control and air surveillance.
