The Defense Solutions division of Curtiss-Wright Corp. has completed the development phase of a contract from South Korean defense contractor LIG Nex1 to supply commercial-off-the-shelf (COTS) radar processing module technology. The technology is targeted for the Korean Army’s Next-Generation Local Air Defense Radar and Korean Air Force’s Long-Range Surveillance Radar programs.

As part of the contract, Curtiss-Wright provided its latest OpenVPX modules to LIG Nex1, along with a variety of supporting modules. The latter  includes a high-performance field-programmable gate array (FPGA), single-board computer (SBC), digital signal processor (DSP), network switch, and FPGA mezzanine card (FMC) modules.  

The open-architecture modules enable the pulse compression and beam-forming functions for LIG Nex1’s surveillance radar systems. The development phase for the two radar systems began in 2012 and was recently completed. LIG Nex1 has shown advanced radar technology capabilities during the three-year development period. These include performing multiple digital beam-forming and pulse-compression techniques using radar signal-processing algorithms with several of the Curtiss-Wright SBC modules. Curtiss-Wright manufactured the modules for this contract at its facility in Ottawa, Ontario, Canada.
