RESONANT BEHAVIOR MEASUREMENTS AND TWO-DIMENSIONAL IMAGING OF SMALL CONDUCTING SPHERES IN CATR

By S. Quan and Q. Liu

Full Article PDF (351 KB)

Abstract:
Based on swept frequency RCS measurements system, foam column and proper data processing procedure, the resonance curves of conducting spheres with RCS below -32.95 dBsm are achieved in a single reflector Compact Antenna Test Range (CATR), with measurement errors within 1.0 dB over most of the measurement frequencies. Nine spheres down to -49.01 dBsm are clearly imaged with Range-Doppler (R-D) method and pointwise vector background subtraction technique.
