L MEASUREMENTS OF HIGH-FREQUENCY SCATTERING BY A PARABOLOIDAL REFLECTOR. Experimental measurements were conducted on 18-inch-diameter, waveguide-fed and 24-inch-diameter, cross dipolefed, paraboloidal antennas over a range of frequencies and aspect angles with various combinations of transmit receive polarizations and feed dipole orientations. 1 Simple mathematical formulas were developed for nose-on radar cross section RCS as a function of load impedance and transmitreceive polarization. 2 Possible out-of-band RCS reduction methods were investigated and models made for testing. 3 RCS phase information on the antennas was also obtained as approximated by an empirical expression over the frequencies of interest.
