The Synchronization Transceiver Design and Experimental Verification for the LuTan-1 SAR Satellite

open access: yes, 2020
The deviation between the two oscillators in BiSAR systems will cause a residual modulation of echo signal. Therefore, the phase synchronization is an important issue that must be addressed for BiSAR systems.
