Please explain the purpose of operation: |
The 3d-Radar GPR device is an ultra-wideband emitter regulated under the Part 15 rules and for the purpose of surveying sub-surface and below ground structures. Pursuant to a grant of this STA request, CW will conduct demonstrations of the new 3d-Radar GPR devices for prospective non-federal customers. These devices will operate with frequency steps of 10 MHz or 20 MHz, cycle speeds of 300 microseconds or 150 microseconds, respectively, and dwell times of 1 microsecond. Devices operating with 20 MHz frequency steps are best suited for shallow depths in combination with high resolution (e.g., asphalt, concrete damage detection, and void detection in shallow to medium base). Devices operating with 10 MHz frequency steps are optimal where deeper depth is needed (e.g., void detection in deep base layer). Experimental activities will be of limited duration for a few hours each day on selected days and at selected locations in the U.S. as determined by the prospective customer. |
