VRT protocol improves interoperability, maintainability, and upgradability.
New technology offers engineers of Software Defined Radio (SDR) systems diverse opportunities to apply digital signal processing much closer to the antenna than ever before. Various strategies include the latest wideband data converters, monolithic receiver chips, compact RF tuners, and remote receiver modules using gigabit serial interfaces. Each approach presents benefits and tradeoffs that must be considered in choosing the optimal solution for a given application.
The latest Virtex-7 FPGAs from Xilinx deliver significant benefits for radar systems compared to previous-generation devices. Higher-density silicon with lower power consumption, more resources, faster interfaces, and more and faster memory not only enhances performance, it also opens new application spaces.
