Abstract Wide-band imaging technology has widely been used in military and civil fields. Imaging simulation technology has also developed rapidly and wide-band imaging target simulation technology is the focus of development. At present, in-band flatness and signal coherence are the important factors that affect the simulation accuracy of imaging targets. Based on the analysis of all-phase algorithm, this paper presents a method of phase error selfextraction for wideband imaging system, and designs the structure of system phase error extraction based on system self-built echo. Finally, the experimental results show that the phase extraction error of wideband imaging target simulation system is less than 0.4%.
