SCI-326 Research Task Group (RTG) #2 Meeting on Electronic Support Techniques Enabling Cognitive Electronic Warfare, 19 November, 2020 virtually
State-of-the-art EW systems are vulnerable against emerging tactical communications and radar systems with flexible software defined radios (SDRs) and tunable RF frontends which enable these systems to execute highly reactive and adaptive electronic protection (EP). The ability of radars and radios to change their waveforms and medium access protocols challenges traditional signal detection and identification techniques. To maintain the capabilities of signal interception and interpretation, new identification and classification methods are needed. Thus, SCI-326 aims at assessing how machine intelligence (MI) can be used to detect, classify and assess communications and radar networks in NATO relevant scenarios. In support of this assessment, the team has focused on evaluating machine learning and artificial intelligence (ML/AI) algorithms for electronic surveillance of cognitive and adaptive radio frequency (RF) threats, and in particular, their ability to learn the behavior of such threats when subjected to environmental factors such as RF interference. A primary goal of this group's investigation is to determine a technical framework which can enhance both our NATO partners' cooperation and their effectiveness using MI enabled ES techniques against state-of-the-art and evolving RF threats. Last week, SCI-326 held its second meeting, where each team member presented their novel ES approaches to characterise both communications and radar networks. The next meeting will focus on defining and generating data for a common threat database that all NATO partners in SCI-326 can use to evaluate their MI-enabled ES algorithms. This will include a talk from the NATO next-generation database task group, as well as SCI-227 ST (Directed Energy Weapons (DEW) related Capabilities: Near, Mid, and Long Term Prospects) their investigation into the evolving capabilities of cognitive radar.
