EVS-EN 302 066 V2.1.1:2017

The present document specifies the requirements for Ground- and Wall- Probing Radar imaging systems applications.
Ground Probing Radars (GPR) and Wall Probing Radars (WPR) are used in survey and detection applications.
The scope is limited to GPR and WPR radars, in which the system is in close proximity to the materials being
investigated. It does not include radars operated from aircraft or spacecraft.
The GPR/WPR applications in the present document are not intended for communications purposes, and the intended signal is not radiated into free space.
NOTE: Equipment covered by the present document is intended to be used by competent professional personnel.
The present document applies to:
1) Ground Probing Radars (GPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly
downwards into the ground.
2) Wall Probing Radars (WPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly into a
"wall". The "wall" is a building material structure, the side of a bridge, the wall of a mine or another physical
structure that absorbs a significant part of the signal transmitted by the radar.
These equipment can either:
1) be fitted with integral antennas and without antenna connector; or
2) use different imaging heads (antennas) with an antenna connector, to allow operation at different operating
bandwidths frequencies.
Equipment covered by the present document operates in accordance with ECC/DEC(06)08 "ECC Decision of
1 December 2006 on the conditions for use of the radio spectrum by Ground- and Wall- Probing Radar (GPR/WPR)
imaging systems" [i.2].
These radio equipment types are capable of operating in all or part of the frequency bands given in table 1.
Table 1: Permitted ranges of operation
Permitted range of operation
Transmit 30 MHz to 12,4 GHz
Receive 30 MHz to 12,4 GHz
NOTE 1: Limits in table 2, clause 4.3.4 are to be met.
NOTE 2: The frequency usage conditions for GPR/WPR are not fully harmonised in the EU and CEPT. Some
National Regulatory Authorities (NRAs) may not have a general frequency allocation for GPR/WPT and may
have established individual licensing requirements (e.g. registration of the user). Annex 2 of [i.2] gives some guidance to administrations.
