Sandmeier geophysical research is a small geophyisical company specialized in the development of software algorithms for seismic (reflection and refraction) and Ground Penetrating Radar (GPR) processing and interpretation for near surface applications.
Sandmeier geophysical research - небольшая геофизическая компания, специализирующаяся на разработке программных алгоритмов для обработки и интерпретации сейсмических данных (отражение и преломление) и георадаров, проникающих в грунт (GPR), для применения вблизи поверхности.
Reflex is one of the world's most popular geophysical near surface processing and interpretation packages.

Reflex-W is a near surface geophysical software programme which allows the user to process and interpret wave data, commonly used to interpret 2D and 3D Ground Penetrating Radar (GPR) or Seismic datasets (i.e reflection, refraction, tomography and crosshole). Reflex-W is the complete software package which includes Reflex 2D and 3D allowing the user to easily import data from a number of formats including SEG-Y, SEG2 and is compatible with a wide variety of GPR systems/formats including GSSI, RAMAC, Pulse-Ekko, Utsi, RAMAC etc.). 2D Radargrams can be processed in single files or batch files by editing, static correction, deconvolution etc. The user will also be able to pick the first arrivals, conduct single-shot processing and conduct a velocity analysis of the data. Reflex-W also allows you to process your data from your 2D radargrams into a complete 3D dataset in the XY plane and can be displayed or tracked in X, Y or Z slices (Cube display).

Reflex 3D scan is also available for Reflex-W users. When interpreting the 3D data, the precondition is that the data must have been acquired along equidistant parallel 2D-lines on a regular rectangular grid. This means that the trace increment in one direction (x or y), the start position of the 2D-lines and the scan increment between the 2D-lines must be equal. The data may have been stored on individual 2D-files or within a 3D-file. If stored within a 3D-file the end-positions of the internal 2D-lines must be identical in addition as well as the number of traces into profile direction. The trace increment must be given within the original data.

It covers the complete range of wave data (seismic, GPR, ultrasound) and with the different geometry assemblings (surface reflection and refraction, borehole crosshole and tomography and combination of borehole and surface measurements) is therefore suitable for
