TÜBİTAK

TÜBİTAK Marmara Research Center Materials Institute Underwater Acoustic Laboratory (UAL) has been built in order to develop the critical SONAR technologies in the field of underwater acoustic, as a work package of “National Sonar Wet-End Production and Integration Project for MİLGEM Programme”. Because of lacking such a technology in Turkey, this infrastructure was designed in coordination with Undersecretariat for Defence Industries (UDI) and MİLGEM Project Office (MPO) to develop Wet - End Part of National Sonar and to realize performance tests. Underwater Acoustic Laboratory is initial and unique infrastructure in Turkey to carry out Research & Development,  Test and Calibration activities in the field of underwater electro acoustic transducers. Underwater Acoustic Laboratory has been accredited by German Accreditation Agency (DAP - Deutsches Akkreditierungssystem Prüfwesen GMBH) in 2009. TURKAK (Turkish Accreditation Agency), being the sole accreditation body in Turkey, has accredited UAL in 2014. The main infrastructure is the acoustically isolated open test tank of 15m x 10m x 7,5m dimensions. Besides, open test tank has high accuracy positioning system in order to position the various sensors and sensor arrays of 100 kg and 3000 kg weight. The primary and secondary level calibration of electro-acoustic transducers in the frequency range 2 – 120 kHz in open tank is accredited to ISO 17025. The laboratory is extending calibration capabilities up to about 1MHz (validation is completed up to about 500 kHz). The laboratory carries out research projects to model, design, prototype and characterize various underwater electro-acoustic transducers and arrays.
Underwater Acoustic Laboratory has been announced as a Designated Institute responsible from National Standards in Turkey in the field of underwater acoustics in 2012 by BIPM ( Bureau International des Poids et Mesures) and became associate member to EURAMET  (European Association of National Metrology Institutes) in 2013.
