FPGA signal processing for radar/sonar applications
Dec 1, 2007
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....
Complex antenna system simulation uses EM software
Dec 1, 2007
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....
