Event description

Description

Since the 2nd World War and during the Cold War, the air defense radar has proven to be the main surveillance sensor, where each radar would cover a radius of more than 200 nautical miles. Apart from the electronic warfare, more recently the emergence of stealth or low observable technology, the evolution of ballistic and cruise missiles, as well as the democratization of UAVs (Unmanned Air Vehicles) or drones, have contested the capabilities of the typical surveillance radar. All these targets are difficult to detect, because they exhibit low RCS (Radar Cross Section), potentially flying at the upper or lower limits of the radar coverage or outside the expected velocity range (being either too slow, e.g. some UAVs, or too fast, like ballistic missiles).

The lecture will adress a plethora of topics, including the estimation of the RCS of various potential targets, as a function of the radar frequency band. In this way, the expected detection range against a set of targets can be calculated, for any given radar. Different radar types are taken into consideration, such as low frequency band radars or passive/multistatic radars, examining the respective advantages and disadvantages. Finally, some issues will be discussed concerning the “kill chain” against difficult-to-detect targets, in an effort to defend efficiently the air space.



Speaker:

Dr Konstantinos C. Zikidis graduated in 1993 from the Hellenic Air Force (HAF) Academy, as Telecommunications – Electronics Engineer (MEng). His first assignment was at 114 Fighter Wing (Mirage F1 / Mirage 2000 aircraft), in which he served as Engineering Officer until 2001. Then, he was assigned to the HAF General Staff as staff officer for Avionics/RADAR/Flight Simulators. Since the end of 2004 he served for 3 years as Liaison Officer in Paris, France, overseeing the Mirage 2000-5 programme implementation. After his return from France, he has served in several posts, at the HAF Support Command, the General Staff and the Military Office of the Minister of National Defence, and from Aug. 2013 to Feb. 2015 he was appointed as Support Director at the Calibration Agency of Greece.He is currently the Head of Department of Radionavigation and Meteorology at the HAF Support Command, Elefsis Air Base, Greece.


In 2002 he received his Ph.D. degree from the National Technical University of Athens, School of Electrical and Computer Engineering, Division of Signals, Control and Robotics. His research was focused on neuro-fuzzy function approximation, mobile robotics and reinforcement learning. His interests now include avionics, radar systems, stealth and anti-stealth technologies. He is a lecturer at the HAF Academy and the HAF Technical NCO Academy. He also teaches at the MSc program delivered jointly by the Hellenic Army Academy and the Technical University of Crete, Greece.

He has published more than 25 papers in journals, books and conferences.
