The main research activity of the RADAR project is into the new generation of configurable "smart" microwave transceivers by combining nanotechnology with micro/nanoelectronics and pioneering 2D and 3D heterogeneous integration, creating products with increased functionality that extend beyond state-of-the-art technology and innovates in the transceiver market by exploiting one "Unique business window opportunity" for applications from future 5G wireless networks to upcoming radars. The project has three years duration (from May 2018), seven institutions cooperate and the coordinator is the Foundation for Research and Technology (FORTH) of Crete. The Hellenic Naval Academy as a partner has to design and optimize the GaN MMIC circuits, namely the High Power Amplifier (HPA) and the Low Noise Amplifier (LNA). Modeling will be done using electronic design and electromagnetic simulation software such as ADS, HFSS, EMPro and CST to achieve optimization of performance. The design library will be completed in parts through a sufficient number of feedback cycles to design, construct, characterize and compare between computational and experimental data.


(2) FREE SPACE OPTICAL SYSTEM:Τhis project is in collaboration with the Physics Department of the University of Athens – Department of Electronics, Telecommunications, Computers and Automatic Control. The project concerns the installation of a Wireless Optical System FSO between the Hellenic Naval Academy and the Lighthouse of Psyttalia (belonging to the Hellenic Navy). The system has been funded by the Hellenic Navy and it was installed in 2011. The system operates since then uninterruptible and measurements of the capacity (bit rate) and of the bit error rate are continuously taken to be compared with theoretical data of the joint research team between Hellenic Naval Academy and University of Athens. The purpose is to compare the data in order to accurately study the influence of the atmospheric and weather conditions to the system performance and conclude on its optimization with respect to maximum bit rate, fading, outage probability and overall reliability. Ultimate target is the use of such systems for the transmission of real data of the Hellenic Navy because FSO systems offer high security (cannot be intercepted) and cannot be jammed by potential interferers.


(3) EXPERIMENTAL SYSTEM OF THREE AXES MAGNETIC MEASUREMENTS IN A SCALED SHIP: The ships’ static magnetic fields are produced from ferromagnetic materials and include: (a) Permanent magnetism (PM) due to the ship's hull, engines or other large vessel ferromagnetic components and (b) Induced Magnetism (IM) caused by the presence of the ship in the Earth's magnetic field. Given this theoretical background, on a scaled "model" vessel in marine environment, experimental and research work was carried out as follows: (a) Measurement, storage and analysis of permanent and induced magnetic disturbance data and (b) Calculation and indication of the desired current settings in the antimagnetic cable to improve and reduce the magnetic signature of the ship.
