Complex antenna system simulation uses EM software 
Dec 1, 2007 12:00 PM, By Steve Rousselle, Michael Miller and Arien Sligar
The sophistication of circuit and 3-D EM simulation tools has reached a point where complex system-level behavior may be simulated prior to fabrication. When EM simulation is combined with circuit simulation, the result is a powerful platform for the design and testing of complex antenna systems. Several enabling simulation techniques allow complex designs, while replicating real-world system-level behavior in these applications....

FPGA signal processing for radar/sonar applications 
Dec 1, 2007 12:00 PM, By Ryan Kenny
FPGAs have been used in radar and sonar systems for some time—mostly in support functions. However, as FPGAs get more sophisticated, performing and integrating more DSP functions in FPGAs is becoming the standard. As a result, radar- and sonar-system designers can rely on logic providers for optimized processing solutions, rather than on proprietary math functions....

Addressing the physical security of encryption keys 
Dec 1, 2007 12:00 PM, By Swati Joshi
Physical security of an encryption key is of prime consideration in military applications. However, it is possible to achieve compliance with applicable regulations, as well as provide additional layers of protection, using specially designed components. These components use electrical and physical design techniques for the secure generation and storage of digital encryption keys....
