ISAR Imaging of Ship Target Based on LMSF Signal
To obtain high resolution ISAR image of ship target in motion with narrow-bandwidth T/R devices and a low-speed A/D sampler,an effective imaging method based on Linearly Modulated Stepped Frequency (LMSF) is proposed in this paper.Firstly,the signal model is developed and analyzed.Secondly,a band coherent processing method is proposed to eliminated the error induced by the translational motion and the high range profile is obtained.Finally,the high resolution of cross range is achieved by using the DechirpClean techinque. The theory analysis and the resutl of real data processing demonstrate the performance of the proposed method.
