Radar and other digital processing systems are by their very nature complex and challenging to configure. Depending on the system architecture, the radar program’s team of software, hardware, FPGA and system engineers might require four to eight weeks to optimize the configuration of the board level modules selected for their particular project. This phase of [...]
Many military satellite communications (SATCOM) systems operate in the very-high-frequency S-band (2 to 4 GHz) and C-band (4 to 8 GHz) range. Accurate sampling of satellite communications requires frequency rates that are at least twice, but preferably 2.5 to 3 times, the speed of the carrier frequency.
Several design approaches exist for implementing beamforming processing tasks, with options ranging from GPUs to multicore CPUs, DSPs, and FPGAs. The unique strengths of FPGAs make them an increasingly appealing choice for beamforming when compared to their counterparts.
Designing a general-purpose FPGA DSP card for EW, radar applications using the latest generation of FPGAs
Designing a general-purpose FPGA card that addresses the universe of Electronic Warfare (EW) and radar applications is a challenge. For any individual application, defining the requirements of the system and determining the optimal architecture for that particular solution is fairly straightforward. However, the problem is much more complex when trying to target a wide spectrum of use cases with a single FPGA module. The goal is to provide a flexible architecture that also enables the use of the latest FPGA features.
