    摘要: A municipal infrastructure maintenance system uses a ground vehicle to move an antenna array in back-and-forth sweeps over large areas or distances. The antenna array comprises dozens of compartmentalized radio dipole antennas arranged laterally, shoulder-to-shoulder across the width of each sweep. An antenna switch matrix is connected between the antenna array and a ground-penetrating-radar (GPR) set and provides electronic aperture switching and selection, and the ability to laterally register one sweep to the next. The antenna array is extended out in front of the ground vehicle on a pivotable boom, and the cantilevered weight is a primary concern. The antenna array is constructed with aluminum-on-aluminum honeycomb panels slotted and folded around dozens of resistive-card compartment separators. Printed circuit boards with matching baluns are also slotted to receive tabs on the resistive cards, and their dipole elements are resistive loaded to quench crosstalk and near field effects.
