MAM- UYTL

Ten years have passed since the establishing of the International Laboratory of radiophysics profile. In this program scientists from two countries Turkey and Ukraine are working together.

10 years of successful and efficient cooperation convincingly proved effectiveness of such format of cooperation and allowed to accumulate unique experience of international projects organization.

Starting from this issue, our site will permanently inform you related current projects development in the Lab.

And, in our turn, we’ll be glad to receive comments or proposals for from you.

ILHT (International Laboratory For High Technologies) was established between TUBITAK and Ukraine Ministry for Science and Technology with a protocol under the name “Turkish Ukrainian Joint Research Laboratory in February 1997.
The aim of the laboratory is to create cooperation about joint scientific and technological research areas and share the results. Marmara Research Center was decided as the location of the laboratory due to her mainly scientific and technological research and development structure. It was also decided that Prof. Dr. Alexey Vertiy (Alex.Vertii@mam.gov.tr) was appointed as the director of the laboratory.
The laboratory’s name was changed as its present name- International Laboratory For High Technologies (ILHT)- with a new protocol between TUBITAK and Ukraine Ministry for Science and Technology on 8th October, 2003 (see the charters of ILHT). It was particularly expressed the important place of ILHT in the scientific and technological cooperation between two country in “The Joint Action Plan Between The Cabinet Of Ministers Ukraine and The Government Of The Republic of Turkey On Enhanced Cooperation” (see The Joint Action Plan) on 2nd April 2004.

The primary areas that ILHT are involved:

1 director, 2 senior researchers, 3 junior researchers, 1 senior technician, 1 junior technician are employed in the laboratory. Research and development activities about electromagnetic wave technologies in the wide range from 100 kHz to 100 GHz are done in ILHT. Following R&D activities of ILHT are listed below:

Several prototypes have been prepared till now, they are the products of several projects supported by Ministry for Defense, Turkish Armed Forces, DPT, TUBITAK and Israel Magal Security Inc.
25 international scientific paper and about 75 international oral representation have been published the activities in ILHT.
There is close cooperation between GIT (Gebze Institute of Technology) and Kocaeli University

Several subsurface sensing prototypes to detect moving people and new generation microwave detection system have been developed in ILHT. The definitions of them are given as follows:

Fig.1 Microwave Detection Radar is in test area for through wall human
detection.

Microwave Detection Radar can be seen in test area for through wall detection in Fig.1. A diagram of through wall detection of person using Microwave Detection Radar is given in Fig.2. Trace of the person in time and position axis can be seen as red and green trace on the computer screen in real time. A person staying under a layer of soil is detected in Fig.3.
Search and rescue radar, another application, is detecting a person under the simulated ruin supplied by Kocaeli Municipality Search and Rescue group after 1999 earthquake. The breathing is seen on the computer screen as a periodic signal.

Fig. 4 Search and rescue radar, another application, is detecting a person under the simulated ruin supplied
by Kocaeli Municipality Research and Rescue group after 1999 earthquake. The breathing is seen on
the computer screen as a periodic signal.

It is aimed to detect an intruder close to a border fence combining new technology radar. All the parts, hardware and software, are developed in UYTL. The system is capable to detect person from 15-20 m. away in open area depending air condition. The data is sent to central computer using blue tooth technology. A creeping intruder is detected in Fig.5. Detection signal increased when he is closer to the fence.

is closer to the fence.

This system is based on microwave tomography and used for detection and visualization of dielectric (plastic) materials that is not possible to detect by conventional detection systems such as metal detector. Slice to slice images of observed object both in depth and height is shown on the screen after mechanical scanning and processing data. Inverse problem and tomography algorithms are used for data processing. The position and the image of subsurface object are visualized on the computer screen. All hardware and software of the setup are developed in UYTL. The photograph of the prototype, reconstructed images, slice-to-slice and 3-D, after scanning of a plastic object and reconstructed images of plastic and metallic pipes located under ground 20 cm below are shown in Fig.6.

B) Microwave Non destructive Tomography Prototype:

Inhomogeneties in dielectric can be detected nondestructively by this prototype. The prototype can be used, as a civil engineering application, to visualize reinforcement quantity in a concrete block (Fig.6). The prototype is composed of a laptop computer, data acquisition hardware and software and receiver- transmitter antennas. Cracks and defects inside the dielectric material are also visualized.

4) Eddy Current Nondestructive Evolution Tomography Prototype:

Eddy current is a well-known and practical method for nondestructive evolution of surface cracks of metal species. UYTL first compose eddy current and tomography in a one prototype. Cracks are visualized slice to slice for each depth by this novel technique. Even inner cracks can be detected by tomography method. The photograph of prototype and reconstructed images of standard cracks in aluminum sample and simplified schematic diagram of rivet junction and their reconstructed images below are shown in Fig.8.
