Zond-12e GPR system shielded air launched 1.0 GHz antenna unit is general purpose antenna with coupled transmitting and receiving antennas in strong housing, designed for shallow penetration depth, roads inspection and concrete profiling with 10 cm resolution* in asphalt.

Antenna operates from surface and lifted position up to 10-20 cm above the ground.

* 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.
