GPS Insurance: Antijamming the System
Don Herskovitz
The Global Positioning System (GPS) has become increasingly relied upon by the military for a number of critical applications from navigation to the delivery of precision weapons. Like any other radio-frequency system, though, GPS is not invulnerable to jamming. JED looks at ways to protect GPS from jamming.
ON THE COVER: GPS jamming could have dire consequences for both the military and civilian sectors. (Cover by R. A. Pike)

Designer Polarization for EW Antennas
Robert O. Magatagan
Historically, EW systems have employed cavity-backed spiral antennas, but these were unable to meet the challenges posed by arbitrarily polarized, hostile signals. JED showcases one antenna design that can meet such challenges: the dual-polarized sinuous antenna.
Protecting the Big Boys: Directed IR Countermeasures for Large Aircraft
They're big, slow and fly low. Large aircraft like the C-130, C-17 and C-160 present easy targets to IR-guided surface-to-air missiles. JED examines some of the directed-IR-countermeasures programs currently underway to help protect these work horses of today's air forces from the increasingly sophisticated and highly proliferated IR-missile threat.
Don Herskovitz
Signals-intelligence (SIGINT) systems now employ a range of new approaches to detect and intercept battlefield radar and communications. JED profiles these intelligence systems provide information vital to the warfighter.
