Radar Target Identification through Electromagnetic Scattering Studies

摘要

Radar target identification using electromagnetic scattering is discussed. Frequencies being used are those corresponding to wavelengths from half the target size to one-tenth the target dimensions. The frequency domain calibration of the free field radar range at the Naval Postgraduate School is performed and validated on several perfectly conducting metallic spheres. Measurements of the radar cross section and the phase of the return on several finite length, thin walled, right circular cylinders were done.
