Measurements at 2.86 GHz of the backscatter matrix of 57 spheroidal samples at all aspect angles in the low-resonance region are presented. Sample size ranges up toka = 3.4, and axial ratios of 0.5, 0.6, and 0.8 have been used. Dielectric constants include 2.6, 3.3, and 6.5. The presentation is in terms of circular polarization, but the results are readily convertible to linear (or any other) polarization.
