Abstract：The application of narrowband inverse synthetic aperture radar（ISAR）imaging processing methodscontributes to the precise detection of space group target.However，due to variations in the motion states of group target，the imaging results may exhibit significant blurring，thereby limiting the capability to detect targets within the group.To addressthe above problem，a scenario imaging and target detection method forspace group target based on ISAR processing framework is presented. Initially，Chirplet components extracted from different range cels based on motion feature consistency association ensure the correspondence betweenthe targetand its components.Subsequently，by establishingacost function，individual target velocity deblurring is achieved，providing efective estimation of target motion parameters.Finall，experimental results from numerical simulations prove the effectiveness of the proposed method and its enhancement for group target detection performance.

Keywords：narrowband inverse synthetic aperture radar （ISAR） imaging；group target detection； Chirplet component correlation；velocity blurring；parameterized motion compensation
