Description	GRORADAR is a software package to acquire, process, display and model ground penetrating radar data. It can acquire ground penetrating radar data from digital sources in the DZT, DT1 and RD3 data formats, or read arbitrary digital data with user described formatting. It will also digitize and process older analog data with separate range gain and time calibration files. Processing or manipulation of the image data includes ringing and background removal, noise filters, edge enhancement, horizontal rubber sheeting to known marker locations, topographic correction to EDM surveying data, complex parabola fitting (for object size, object depth and intervening material velocity estimation), 2D velocity migration. Single wavelet scans may be extracted, and then full-waveform, far-field modeled in one dimension, including fully dispersive, frequency dependent electrical and magnetic properties. From the dispersive model material property results, sand-clay-water-air-iron mixture concentrations may be estimated. After calibration with a metal plate, automatic modeling is possible for asphalt or concrete pavement thickness, including a statistical estimate of uncertainty. The modeling portions may be used without data to forecast how well ground penetrating radar may work at a site. Hardcopy output may be obtained at any point in the processing or modeling to HP-GL and PostScript printers. A free demonstration version is available.
