Abstract
Phase fluctuation is one of the inherent characteristics for complex radar targets.The primary objective of this work is to compare the phase fluctuation characteristics of ships on sea surface with that of the sea clutter based on complex high resolution range profiles (HRRPs). The statistics of the HRRP phase gradient are studied using alpha-stable distribution. Numerical simulation results show that the HRRP phase gradient of a ship on sea surface behave significantly different from that of the sea clutter, suggesting that the statistics of HRRP phase gradient provide useful information for ship discrimination from sea clutter.
