Abstract
ABSTRACTA broadband resistively loaded modulated scatterer (RLMS) is developed for ground penetrating radar experiments and optimized to reflect signals that are high in strength and have a flat frequency response with a linear phase variation. The linear phase makes the scattering compact in time and easily interpreted in the time‐domain. A novel method of measuring the modulation with a standard network analyzer is presented, and two example measurements are presented. The RLMS is used to measure the two‐way pattern of a pair of Resistive‐Vee dipole antennas, and to measure the response of a scatterer in soil with a moving water table. The RLMS performs well in these experiments. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1557–1561, 2014
