Enabling cognition on Electronic CounterMeasure systems against next-generation radars

Abstract

Current Electronic CounterMeasure (ECM) systems process preprogrammed jamming techniques against radar threats that are captured and identified by Electronic Support Measures (ESM) systems. On the other side, with recent technologies, radar systems become adaptive and intelligent systems that can change their waveforms. Nevertheless, ongoing studies in the radar domain have enabled cognition. However, an ECM architecture is yet to be developed for automatically generating effective countermeasures against new, unknown and next-generation radars. To address this need, enabling a cognitive control mechanism in the ECM system is a suitable solution. In this paper, we present an architecture for Cognitive Electronic CounterMeasure (CECM) system. This CECM system assesses the most effective ECM technique against new, unknown and adaptive or cognitive radars. Simulations reveal that CECM system provides accurate mapping performance while providing satisfying generalization for unknown emitters.

High-Quality Radar Pulse Signal Acquisition and Deinterleaving under a Low Signal-to-Noise Ratio with Multi-Layer Particle Swarm Optimization

“…Step 2: Grouping and accumulating the signal with particle parameter according to Equations from (6) to (12).…”

“…In radar EW, the electronic support measure (ESM) [3][4][5][6][7][8][9] can provide practical military intelligence and battlefield spectrum awareness through the feature estimation of reconnaissance signals. Based on the information obtained by ESM, effective electronic countermeasures (ECM) [10][11][12] can be easily generated to counter specific radar sources. However, with the iteration and development of radar technology, low probability interception (LPI) [13][14][15][16][17] radar is widely used in practice, which makes the signal power lower than before.…”

Machine Learning Aided Electronic Warfare System

“…Cognitive electronic warfare systems seek to autonomously conduct tasks that would otherwise require human intervention. Cognition is defined as the knowledge required to act or process an event [14]. Fuster's paradigm of cognition states that cognitive agents have the following abilities: perception/action cycle, memory, attention, intelligence, and language [14].…”

“…Cognition is defined as the knowledge required to act or process an event [14]. Fuster's paradigm of cognition states that cognitive agents have the following abilities: perception/action cycle, memory, attention, intelligence, and language [14]. There are four primary tasks for cognitive EW systems: target detection, target acquisition, target tracking, and platform guidance [15], all of which are achieved by the developed system.…”
