Deceptive Jamming Method with Micro-motion Property Against ISAR [PDF]

open access: yesRadioengineering, 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.
