Abstract : Three-dimensional radiation measurements were made of the AN/FPS-3A Radar at the Air Force Radar Station, Ozona, Texas. The measurements made using the EMCO Sphere Technique are summarized. The da a are presented in both the polar and rectangulaees. Polar plots of the data for the 2nd harmonic (0 - 20 degree elevation), 4th h r onic (0 degree elevation only), 5th harmonic (0 degree elevation only) and a spurious frequency (0 degree elevation only are shown. Information is given concerning the equipment arrangements, shielding techni ues, and calibration techniques u plots for the fundamental frequency of the AN/FPS-3A in the form of 360 degrees azimuth cut for each 5 degrees of elevation between 0 to 70 degrees. Polar plots of the data for the 2nd harmonic (0 - 20 degree elevation), 4th h r onic (0 degree elevation only), 5th harmonic (0 degree elevation only) and a spurious frequency (0 degree elevation only are shown. Information is given concerning the equipment arrangements, shielding techni ues, and calibration techniques used. (A UT OR)
