Electronic Warfare (EW) platforms face an increasingly challenging task in terms of RF channel density and signal evasiveness. Curtiss-Wright and Leonardo DRS have collaborated on a range of rugged open architecture RF signal processing systems. The Curtiss-Wright Electronic Warfare (EW) multi-channel tuner system is a ruggedized compact 3U VPX system that combines state-of-the-art multi-channel receivers, Intel® Xeon® D multi-core DSPs, and Xilinx® FPGAs.
