Specialist Task Force 350: Detect-And-Avoid (DAA) parameters and test procedures for Ultra-Wideband communications applications

Who we are:

Team Leader: Sebastian MUELLER, ETSI
Team Members: Friedbert BERENS, STMicroelectronics
Steven ETTLES, Discrete Time Communications      

What we do:

The purpose of the work is to achieve co-existence of UWB communications devices having the DAA mechanism with victim radio services such as broadband wireless access systems, future mobile services systems and radiolocation systems.

For the complete standardisation of the mechanisms, suitable technical parameters and test procedures are needed. These include flexible mechanisms based on multiple detection thresholds and multiple operating zones providing adequate protection levels for victim services as defined in CEPT/ECC-TG3 (e.g. broadband wireless access systems, future mobile services systems and radiolocation systems).

The scope of the CEPT/ECC-TG3 Mitigation technique working group is to define the “DAA regulatory requirements” content and to leave to the standardization committee (ETSI) the responsibility to specify technical DAA parameters and test procedures.

Time plan for the work:

The STF will produce the following deliverables:

DTS/ERM-TG31A-0114 Short Range Devices (SRD) using Ultra Wide Band technology (UWB) for communications purposes.  Scope is to provide a technical description of the DAA mitigation techniques for UWB implemented technologies), covering the following items: DAA-1 (protection of S-band radar), DAA-2 (protection of WiMAX) and DAA-3 (protection of X-band radar).

DTR/ERM-TG31A-0115 Short Range Devices (SRD) using Ultra Wide Band technology (UWB) for communications purposes.  Scope is to provide the different RF compliance tests for the DAA mechanism of UWB implemented technologies.

according to the following time scale:


  • Start of the work mid-February 2008
  • First stable draft TS for TG31A review March 2008
  • Stable draft for TG31A review April 2008
  • Final Draft for TG31A approval 16 April 2008     (TG31A#22)
  • TB approval by delegation to TG31A 17 April 2008     (TG31A#22)
  • Publication End 2008


  • Start of the work September 2008
  • Final Draft for TG31A approval December 2008
  • TB approval 1Q2009
  • Publication 1Q2009


WALTER project:

The validation of DTS/ERM-TG31A-0114 and DTR/ERM-TG31A-0115 requires the availability of radio equipment for measurements as well as test laboratories. Through the WALTER project, test laboratories can contribute free of charge.

Contents of DTS/ERM-TG31A-0114 and DTR/ERM-TG31A-0115 can be used as input to the WALTER project.

About FGAN and FHR:

The Forschungsgesellschaft für Angewandte Naturwissenschaften (FGAN – Research Establishment for Applied Science) has embodied excellence in applied research in the field of military technology for 50 years.

FGAN’s institutes originally began as university workgroups whose research was of high interest for the Bundeswehr (German armed forces). The importance of this research led to the decision that this research be carried out within the framework of a central establishment.

It consists of three research institutes which are predominantly active in the field of Command and Control:


Research Institute for High Frequency Physics and Radar Techniques,


Research Institute for Communication, Information Processing & Ergonomics


Research Institute for Optronics and Pattern Recognition 

FGAN researches and compiles knowledge needed to support and advise the Bundeswehr on its innovative strategies, processes and sourcing.

In particular, the task of FGAN is to identify potential areas of utilization, so that technological advances can be optimally implemented within the specialized environment of military deployment.


About the FGAN Research Institute for High Frequency Physics and Radar Techniques (FHR):

Concepts, methods and electromagnetic sensor systems are developed at the institute, particularly in the field of radar. This is done in close conjunction with novel signal processing methods and innovative technologies in the frequency range from meterwave to lower Terahertz.

The institute’s expertise, which is manifested by highly complex experimental systems that are developed and maintained in-house, covers almost every aspect of modern radar techniques. Thus it secures national client counselling and judgement capability in the field of military technology.

BIO of  FGAN’s STF 350 expert:

Dr. Udo Uschkerat

Udo Uschkerat has 12 years experience in military radio location systems, 10 years experience with UWB GPR devices. The latter experience means a strong background in UWB sensors.  He is a consultant for GE MIL NARFA in ECC TG3 since 2005, there mainly working on coexistence problems of UWB short range devices with (mil.) radiolocation systems.          
Other interests: mine detection, target classification and identification based on radar signal analysis.
