1 Scope
The present document specifies the requirements for Building Material Analysis (BMA) and classification applications
using UWB technology operating in all or part of the frequency band from 2,2 GHz to 8,5 GHz. Additionally, it
specifies reduced emissions in the ranges from 0,96 GHz to 2,2 GHz and 8,5 GHz to 10,6 GHz.
The present document applies to:
a) UWB Building Material Analysis and classification equipment for imaging and object detection applications;
b) equipment fitted with an integral antenna;
c) handheld devices.
The present document does not apply to:
• UWB communication devices; and
• Ground penetrating radar devices; and
• Through-wall radar imaging devices;
as defined in ITU-R Recommendation SM.1754 [i.1].
The present document specifies the equipment which is designed to not radiate into the free space. It is designed to
function only when positioned such that it radiates directly into the absorptive material such as walls and other building
materials which absorb emissions.
The present document does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
activity factor: effective transmission time ratio, actual on-the-air time divided by active session time or actual
on-the-air emission time within a given time window
ETSI

---------------------- Page: 8 ----------------------
9 ETSI EN 302 435-1 V1.3.1 (2009-12)
clutter: undesired radar reflections (echoes) e.g. from inhomogeneities, interfaces, gravel stones, cavities in building
material structures
integral antenna: permanent fixed antenna, which may be built-in, designed as an indispensable part of the equipment
Listen Before Talk (LBT): mechanism to avoid signal transmission in the presence of other radio service signals
Pulse Repetition Frequency (PRF): inverse of the Pulse Repetition Interval, averaged over a sufficiently long time to
cover all PRI variations

NOTE: This is also defined in ITU-R Recommendation SM.1538 [i.2].

wall or other absorptive material to be investigated
NOTE: Undesired emissions are:
leaked emissions from the side or backside of the antenna; and/or

residual emissions through the building material.

1 Scope
The present document specifies the requirements for Building Material Analysis (BMA) and classification applications
using UWB technology operating in all or part of the frequency band from 2,2 GHz to 8,5 GHz. Additionally, it
specifies reduced emissions in the ranges from 0,96 GHz to 2,2 GHz and 8,5 GHz to 10,6 GHz.
The present document applies to:
a) UWB Building Material Analysis and classification equipment for imaging and object detection applications;
b) equipment fitted with an integral antenna;
c) handheld devices.
The present document does not apply to:
• UWB communication devices; and
• Ground penetrating radar devices; and
• Through-wall radar imaging devices;
as defined in ITU-R Recommendation SM.1754 [i.1].
The present document specifies the equipment which is designed to not radiate into the free space. It is designed to
function only when positioned such that it radiates directly into the absorptive material such as walls and other building
materials which absorb emissions.
The present document does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
activity factor: effective transmission time ratio, actual on-the-air time divided by active session time or actual
on-the-air emission time within a given time window
ETSI

clutter: undesired radar reflections (echoes) e.g. from inhomogeneities, interfaces, gravel stones, cavities in building
material structures
integral antenna: permanent fixed antenna, which may be built-in, designed as an indispensable part of the equipment
Listen Before Talk (LBT): mechanism to avoid signal transmission in the presence of other radio service signals
Pulse Repetition Frequency (PRF): inverse of the Pulse Repetition Interval, averaged over a sufficiently long time to
cover all PRI variations
radiated measurements: measurements which involve the absolute measurement of a radiated field
spatial resolution: ability to discriminate between two adjacent targets
Short Range Device (SRD): equipment defined to operate on a non-interference, no protection from interference basis
NOTE: This is also defined in ITU-R Recommendation SM.1538 [i.2].
Total Power (TP): integration of the undesired emissions in the whole area around the Building Material Analysis
(BMA) scenario
NOTE: The integration is over a sphere (same procedure as for Total Radiated Power (TRP)). This value is
comparable to an equivalent isotropic radiator.
undesired emissions: any emissions into free space during operation of the equipment when equipment is faced to a
wall or other absorptive material to be investigated
NOTE: Undesired emissions are:
leaked emissions from the side or backside of the antenna; and/or
scattered/reflected emissions from the building material to be investigated; and/or
residual emissions through the building material.
