Electronic Warfare (EW) involves jamming or spoofing an adversary’s electronic sensing or electronic communications. One common example is detecting communications at a certain frequency and then jamming that frequency. Another example is detecting an incoming radar signal and responding with a simulated return signal indicating a bogus location; for naval surface vessels, this type of electronic countermeasure (ECM) is critical to protection against missile attacks.
System designers building these EW systems need high performance embedded computing that can detect, identify and respond to signals within the brief time intervals characterizing the electronic battlefield. Curtiss-Wright meets the need with powerful modules implementing cutting edge Field Programmable Gate Arrays (FPGAs), Analog-to-Digital converters (ADCs), and Digital-to-Analog converters (DACs). The also offer large banks of Digital RF Memory (DRFM) for radar spoofing and other Electronic Countermeasures (ECM). There are options in both 3U and 6U OpenVPX form factors, delivering the processing power to operate on high bandwidth data streams with very low latency. These open architecture COTS boards are ruggedized to operate in harsh environments.
Curtiss-Wright is collaborating with General Dynamics Mission Systems to deliver open architecture artificial intelligence (AI) based COTS solutions for Signal Intelligence (SIGINT) and electronic warfare (EW) situational awareness applications. The combination of General Dynamics’ SignalEye threat detection software and Curtiss-Wright’s Intel Xeon D processor-based CHAMP-XD1 module provides system designers with a deployable COTS solution for RF spectrum situational awareness that automatically classifies signals through the use of machine learning.
