Digital Beam Former
The Digital Beam Former (DBF) is an indigenisation project where CoreEL has pioneered the beam forming for phased array
RADARs in the digital domain using FPGAs. It was delivered as a turnkey solution.
The DBF uses a modular and scalable architecture which enables it to be efficiently adapted as per new requirements. Two
variants of DBF and its ATE, with different capacities were developed and delivered on the same underlying framework.
DBF accepts the data from front-end of the phased array through optical links, synthesize beams and deliver this data to signal
processing units for further processing. The beam formation is done by algorithmic processing of the received data in FPGAs.
Configuration, control and status monitoring of the DBF unit takes place through Ethernet, it also supports an optical control
link.
