Cooperative Cross-Eye Jamming Against Advanced Radars: Effectiveness and Countermeasures

Cross-eye jamming is an effective electronic countermeasure technique against monopulse radars, introducing controlled phase distortions to degrade angle estimation. Traditional implementations using a single platform face limitations in baseline length and induced tracking error. This study examines a cooperative approach, utilizing multiple platforms such as fighter aircraft and UAVs to enhance jamming effectiveness. The resilience of modern direction-of-arrival estimation methods, based on the compressed-sensing framework, is also evaluated. Simulations of radar-guided missile engagements assess the impact of various jamming configurations, providing insights into countermeasure effectiveness and potential mitigation strategies.
