Python xGPR is a next generation Real Time Sampling single-unit low-frequency GPR. The main advantage of the system is an expanded dynamic range (up to 138 dB) and high data rate, that converts to the huge stacking (up to 65536 times), it gives a jump up for a Signal-To-Noise ratio, drops down noise floor, deepens penetration, helps to distinguish weaker signals than ever before. 

The user is getting a real-time information as a radiolocation profile (sometimes also referred to as radargram). Data are recorded on a hard disc for further use (processing, printout, interpretation, etc.) at the same time. You will see examples of radiolocation profiles here...

The full set of Python xGPR contains a built-in control electronics, battery and Wi-Fi router on the 100 MHz unshielded antenna, additional antenna extenders to change the antenna central frequency (50 / 38 / 25 MHz), antenna noses and accessories.

There are different types of the positioning devices which could be used with the Python xGPR: wireless survey wheel and Multifrequency RTK GNSS receiver zBell.

All georadar parameters are computer controlled, therefore many hardware operation features are described here...

* Relationship between resolution and sounding depth is assumed that sounding is made in a soil whose relative dielectric permittivity is equal to 4 and specific attenuation is 1 to 2 dB/m. Depth of investigation is understood to be detection depth of a flat boundary with reflectance equal to 1. Note that these data are rather approximate and are strongly dependent on parameters of the environment sounded.
