A Study on ISAR Imaging of Ship Targets on Sea for Airborne Radar

ISAR imaging technology is an important method of classification and recognition for ship targets.In this paper an airborne radar ISAR imaging algorithm for ship targets at high sea state is proposed.It consists of range profile alignment by iterative cross-correlation,phase compensation by the improved ROPEauto-focus technique and an instantaneous imaging method by parameter estimation of multi-component AM-LFM signals on the basis of clean technique.The imaged result of radar data verifies the validity of...
