Deceptive Jamming Method with Micro-motion Property Against ISAR [PDF]
Radioengineering, 2017 Airborne target's micro-motion such as rotation or vibration causes phase modulation, termed as micro-Doppler effect, into radar signals. The feature of micro-motion is one of the most obvious features for radar recognition in mid-course phase.

Deception jamming method based on micro‐Doppler effect for vehicle target
IET Radar, Sonar & Navigation, 2016 Ground moving target is the main concern for ground surveillance radar. To protect the manoeuvring target from being detected by radar, some jamming technologies are utilised. In this study, a novel method of deception jamming for vehicle target against continuous wave ground surveillance radar is proposed. Traditional jamming method only considers the
