The Processing Framework and Experimental Verification for the Noninterrupted Synchronization Scheme of LuTan-1 [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2021
The bistatic synthetic aperture radar (BiSAR) plays an important role in remote sensing. However, the deviation between the two oscillators in BiSAR systems will cause a residual modulation of the echo signal. Therefore, the phase synchronization is an important issue that must be addressed in the BiSAR system.
