In response a Specialists’ Meeting, RSM SET-RSM-247, was held in Helsinki FIN on 8, 9 May 2017 in order to present and discuss technologies being developed across NATO with potential for RIBI. There were 16 papers presented and a number of those appropriate for public release have been published in a Special issue of the Electronics letters journal. During the final discussion session of the RSM it was proposed that SET explore the feasibility of conducting a Collaborative Demonstration of Technology (CDT) in order to demonstrate and evaluate different nations’ technologies. This would be against a broad target set (E.g. weapons, people, equipment, interior walls) contained within a realistic building environment. It received widespread support, leading to this TAP for an ET to scope such an activity.
The ET will endeavour to:
• Gauge the level of likely participation and support across NATO for such a CDT
All the representatives at the first ET are keen to support a CDT
• Catalogue the technologies that could be brought to bear, and from who
The technologies presented at the ET were:
- LF Synthetic Aperture Radar (volumetric and through the wall) [GBR, NL]
- Ultra Wide Band Radar [GE]
- mmW Radiometers [GE]
- THz imaging [SI]
- Lidar [GBR]
- Powerline sensing [GBR, USA]
It was also felt conventional sensors should also be included in a trial, and used within the data processing and fusion. These sensors included:
Partner nations should be contacted that may be interested in providing such sensor capabilities.
• Agree an outline experimental design, including potential locations and necessary resources including infrastructure, equipment, personnel and trial support
Trial location: GBR took an action to identify possible trials locations within the UK.
It was felt that a trial should involve imaging/sensing around a small number of buildings, ideally from a stand-off of tens of metres. The trial should be conducted “blind” so that the sensor providers and data processors will be unaware of the specific contents of the buildings or activities taking place. This will require an independent trials team, and careful control before, during and after the trial.
A number of the sensors are not able to operate at significant stand-off, or are still in development meaning that they have not been miniaturised or weather-proofed. This will limit the ability to collect data simultaneously. Careful control will be required to ensure that data sets collected can be suitably compared. Post-trial data processing and development of data fusion will require accurate ground-truth.
The details of a possible trial will be developed over the course of the ET.
• Produce an outline PoW for a putative TG
This will be an outcome of the ET
A number of technological approaches are seen to be relevant such as: multi-aspect LF SAR, non-imaging RF, and non-RF techniques such as lasers, electrostatic sensors and gravitational techniques. An optimum solution may well rely on a ‘fused’ combination of these so to apply and test a range of them against a common target set is likely to provide invaluable information regarding both their relative and combined utility.
