• Gebundenes Buch

Produktbeschreibung

Discussions include: Target support fixtures a plastic foam columns, string supports, metal pylons; unusual methods are also discusses, including one involving no support at all. Calibration a Instrumentation calibration, RCS calibration, primary and secondary standards, calibration by substitution. Outdoor test ranges a Real estate needed, antenna selection, ground-plane optimization, berms, radar fences. Scale-model testing a scaling laws, dielectrics and absorbers, metallic coatings, resistive sheets The electromagnetic principles governing accurate RCS measurements are explained in easy-to-read style. The explanations are supported by simple analyses and augmented by measured and computed illustrations.
