1. Modeling of a Retrodirective Channel With Active Antenna Arrays for Cross-Eye Jamming
Abstract : Cross-Eye (CE) jamming is a technique aimed at inducing false target angles in radar measurements. The potential to deceive monopulse radar, a radar type commonly used due to its angular accuracy and resilience against jamming, has captured the interest of Electronic Warfare (EW) system manufacturers.

2. An electronic warfare perspective on time difference of arrival estimation subject to radio receiver imperfections
Abstract : In order to ensure secure communication in digital military radio systems, multiple methods are used to protect the transmission from being intercepted by enemy electronic warfare systems. An intercepted transmission can be used to estimate several parameters of the transmitted signal such as its origin (position or direction) and of course the transmitted message itself. READ MORE

5. Dual Band Prime Focus Feed for Satellite Earth Terminals
Abstract : Satellite Communication systems have been studied and developed since long. With more high frequency satellite bands coming in the market, there is a need to develop suchsystems with multi-band or wideband operation with reconfigurable antennas which can provide simultaneous transmit receive capabilities on different polarizations as well as have properties suitable to track the satellite.
