Radar Signature Prediction

"With the availability of fast and powerful computational facilities, we are now able to characterize full-scale vehicles. However, recent developments in fast methods and the availability of new hybrid methods that combine integral, differential and highfrequency methods, have yet to be exploited for full-scale radar signature prediction of modern structures that may incorporate composites and radar absorbing materials at various frequency bands. Applied EM proposes to develop a hybrid approach to includefast integral equation solvers coupled with a variety of hybrid methods. We also propose the application of reduced-order models for frequency and angle sweep extrapolation leading for a fast construction of ISAR images. The developed computational toolswill be applicable to both radar signature calculations as well as antenna performance predictions. These tools can also be used in commercial aviation, transportation and for industrial security. Increasingly new applications are also found in the medicalimaging area."
