Project Advanced Radar Absorbers, Final Report
ABSTRACT
The report presents results and activities obtained in the project Advanced radar absorbers during the years 2001-2003.
The goal of the project has been to develop and characterize materials and structures for signature control (low observables),
in the microwave region, of vehicles and other platforms of the Swedish Armed Forces. The project has focused on materials
for high temperature applications, broadband absorbers, nano-composite absorbers and radar absorbing windows. The project
has also focused on measurement techniques for material characterization on microwave and mm-wave band (0.04-40 GHz
for wave-guide measurements and 2-240 GHz for free space measurements). Various materials such as polymer composites,
nano-composites and resistive sheets has been studied and characterized. New optimization methods for radar absorbing
structures based on genetic methods, has been developed. Calculation on bistatic radar cross section of simple shaped objects
covered with radar absorbing surface coating has been carried out and the result shows that for bistatic angles larger than 120
degrees the effect of coating is negligible.
