Method, device, and system for compensating synchronization error

摘要

Embodiments of the disclosure disclose a method, device, and system for compensating a synchronization error applied to a bistatic SAR system in a one-stationary mode to compensate a synchronous error, wherein an echo signal is received in a first channel, and a direct signal directly sent by a transmitter is received in a preset azimuthal direction in a second channel; the echo signal is range-compressed via the direct signal, and a frequency synchronization error is compensated; a range-time trajectory is extracted according to the range-compressed echo signal; and a time synchronization error is compensated according to the range-time trajectory.
