R&D projects

True concept of the company, the R&D and prototyping take a great place into the MC2-Technologies work. The company is engaged into several French and European projects as follows:

 

SPIDER : Synthetic aPerture Interferometric raDiometer for sEcurity in cRitical infraStructure (GRANT#674274)

Along with the evolution of nature and frequency of threats on various critical infrastructures and soft targets, there is a need for evolution and improvement in the detection solutions of hidden objects or materials that can represent a menace to European citizens and assets. Current long queues at airports or administration security checkpoints and bulky scanners will soon be seen as outdated with the coming technologies. As the number of transportation hubs and sensitive location for common security are increasing (airports, power plants, prisons, administrations) passive scanning system, not emitting any radiation, represent the most promising opportunities. Such systems require to tackle ethical issues such as the displaying of personal bodies and still be able to detect hidden objects. Other technical challenges have to be met in order to integrate such detection solution into the everyday life : 3D analysis, real-time detection, spatial resolution. SPIDERS project, built from the results of recent FP7 project to propose the latest passive millimeter wave technology with a synthetic aperture interferometric radiometer. The French company MC2, specialised in radiometric sensors and microwave products and services, aims at developing its business on the rising markets of PMMW technology for security applications and tackle all the stated technical and business challenges to demonstrate a fast 3D scanning system of walking people and detection of hidden objects and materials.

 

DRAC2 :Digital RAdiometric Correlation Camera

 

This project is supported by the French ministry of Defence (DGA) in the frame of a RAPID program. The main aim of this project is to develop a new generation of passive imaging system working at millimeter wave frequencies. The technology is based on an innovative architecture of digital correlation receiver.

PIXEL :

 

MC2-Technologies develops and industrializes microwave scanners solutions for security applications (fight against crime and terrorism). This passive (emission-free) technology is based on a millimeter frequency range variation of radiation of the human body and hidden objects. As part of the PIXEL project, partners intend to improve this technology by enabling real-time display of images without affecting resolution and sensitivity, thus distinguishing themselves from competing solutions. To achieve these goals, mechanical scanning of the existing system will be replaced by a simultaneous reading of the signals received by an antenna array. This instantaneous reading will be obtained by the development of a passive THz multiplexer with time reversal, resulting from the recent work of XLIM.
This project will offer the possibility of producing microwave scanners without equivalent in terms of footprint, performance and speed of execution. To meet these requirements, the technical solution chosen for this project is based on an Synthesis Aperture for Interferometric Radiometer Architecture (SAIR) working in the millimeter wave range associated with the Passive Time Reversal technique (PTR). The latter was originally developed for acoustic applications in order to reduce the number of sensors. In the same vein, the XLIM laboratory of Limoges has transferred the approach of this technique to the development of a MIMO Radar always with the aim of reducing the number of sensors. The main limitation of a SAIR approach is the number of microwave sensors and associated digital acquisition circuits. The use of a time-reversing multiplexer would reduce the number of acquisition circuits by 10 to 25, without reducing the number of antennas (no degradation in resolution and field of view). The use of a time-reversing multiplexer would reduce the number of acquisition circuits by 10 to 25, without reducing the number of antennas (no degradation in resolution and field of view).
The SAIR + PTR association is, to our knowledge, a major innovation as no research on this has been published yet. The success of this combination will considerably reduce the complexity of the entire interferometric reception chain by reducing the numbers of mixers, depressors, low noise amplifiers, analog-to-digital converters and FPGA. This will result in a drastic reduction in cost, consumed DC power and overall footprint, while achieving state-of-the-art performance.
