The Resolution Ability of the Super-resolution ISAR Imaging of Maneuvering Targets
摘要
Abstract
In the ISAR imaging of maneuvering targets, the time-varying Doppler spectrum must be taken into account to produce a focused image,and above all,motion induced errors,such as envelope alignment errors and auto-focusing phase errors,must be compensated to get a high quality image.In this paper, a signal model is first established in which the motion compensation errors and the feature of the target are both treated as parameters to be estimated,then a parameter constraint is proposed to cope with the uncertainty in the signal model,and finally the resolution ability of the super resolution algorithm in the established signal is analyzed.关键词
