A four terminal Gaussian network composed of a source, a destination, an eavesdropper and a jammer relay is investigated when the jammer relay is causally given the source message. The source aims to increase the achievable secrecy rates, whereas the jammer relay aims to decrease it. To help the eavesdropper and to decrease achievable perfect secrecy rates, the jammer relay can use pure relaying and/or send interference to assist eavesdropping. The problem is formulated as a zero-sum game and the saddle point solutions are found. The results are compared to the case when the jammer relay is not informed about the source message.

A Secure Communication Game With a Relay Helping the Eavesdropper Yüksel Turgut, Ayşe Melda; Liu, Xi; Erkip, Elza (2011-09-01) In this work, a four-terminal complex Gaussian network composed of a source, a destination, an eavesdropper, and a jammer relay is studied under two different set of assumptions: 1) The jammer relay does not hear the source transmission, and 2) The jammer relay is causally given the source message. In both cases, the jammer relay assists the eavesdropper and aims to decrease the achievable secrecy rates. The source, on the other hand, aims to increase it. To help the eavesdropper, the jammer relay can use p...
A Secure Communication Game with a Relay Helping the Eavesdropper Yüksel Turgut, Ayşe Melda; Liu, Xi; Erkip, Elza (2009-01-01) In this work a four terminal Gaussian network composed of a source, a destination, an eavesdropper and a jammer relay is studied. The jammer relay does not hear the source transmission. It assists the eavesdropper and aims to decrease the achievable secrecy rates. The source, on the other hand, aims to increase the achievable secrecy rates. Assuming Gaussian strategies at the source and the jammer relay, this problem is formulated as a two-player zero-sum continuous game, where the payoff is the achieved se...
A Survey on s-band phase shifters Kızıltaş, Bilgin; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2013) Phase shifters are essential components of beam directing in electronically scanned phased array radar transmitters and receivers that are used in electronic warfare applications for surveillance and self-protection reasons. In this thesis, initially, fundamentals of phase shifters and various phase shifter topologies are introduced. Afterwards, two-stage all pass filter based phase shifter, eight-section loaded-line phase shifter, aperture coupler based phase shifter and double shunt stub phase shifter cir...
Antenna patterns for detecting slowly moving targets in two channel gmti processing Yıldırım, Gökhan; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2010) Ground Moving Target Indicator (GMTI) is a well-known and widely used signal processing method in airborne and spaceborne radars. In airborne radar and GMTI literature, many radar designs and signal processing techniques have been developed to increase the detection and estimation performance under heavy interference conditions. The motion of the aircraft on which the radar is mounted, high altitudes and ranges, targets with low radar cross sections and slowly moving targets complicates the problem of local...
A Study on the Performance of a Complementary Auxiliary Antenna Pattern for Maisel Sidelobe Blanker DINLER, Dogancan; Candan, Çağatay; KOC, Sencer (2018-04-27) The problem of coupling between probability of target blanking (P-TB) and probability of blanking (P-B) in Maisel sidelobe blanker (SLB) is addressed and a complementary auxiliary antenna pattern is proposed for phased array radar systems. The numerical results indicate that the complementary pattern provides an improvement on P-TB and P-B especially for the cases where antennas have poor mainlobe-to-sidelobe ratio.
