The present document specifies the requirements for Ground- and Wall- Probing Radar applications operating in all or part of the frequency band from 30 MHz to 12,4 GHz.
Ground Probing Radars (GPR) and Wall Probing Radars (WPR) are used in survey and detection applications.
The scope is limited to radars operated as short range devices (because of their usage and design), in which the system is in close proximity to the materials being investigated. It does not include radars operated from aircraft or spacecraft.
The radar applications in the present document are not intended for communications purposes. Their intended usage excludes radiation into the free space.
NOTE 1: Equipment using the frequencies typically below 100 MHz may use higher output power for geophysical applications and therefore, may not fulfil the emission requirements set out in the present document.
NOTE 2: Equipment covered by the present document is normally used by professional, trained personnel.
The present document applies to:
• Ground Probing Radars (GPR) operating over approximately one decade in the frequency range 30 MHz to 12,4 GHz radiating directly downwards into the ground. Any horizontal radiation from this equipment is caused by leakage and is considered as unwanted emission;
• Wall Probing Radars (WPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly into a "wall". The "wall" is a concrete structure, the side of a bridge, the wall of a mine or another physical structure that is dense and thick enough to absorb the majority of the signal transmitted by the radar. This category of equipment does not include products such as "stud locators" that are designed to locate object behind gypsum, plaster or similar walls that are not thick or dense enough to absorb the transmitted signal.
• Equipment fitted with integral antennas and without antenna connector.
• Equipment which uses different imaging heads (antennas) with an antenna connector, to allow operation at different frequencies.
The document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable.
The present document contains the technical characteristics and test methods for Ground- and Wall- Probing Radar applications and references CEPT/ERC Recommendation for SRDs, CEPT/ERC/REC 70-03 .
The present document is intended to cover the provisions of Directive 1999/5/EC  (R&TTE Directive) article 3.2, which states that "... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the R&TTE Directive  will apply to equipment within the scope of the present document.
The document responds to the EC mandate M/329 for Harmonized Standards covering Ultrawideband (UWB) applications .
