Zusammenfassung:A phase synchronization method includes: pulse widths of first and second phase synchronization signals and starting time of transmission of first and second phase synchronization signals are determined, wherein starting time is located between two successive moments when radar signals are transmitted; first spaceborne SAR is controlled to transmit first phase synchronization signal to second spaceborne SAR according to pulse width and starting time of first phase synchronization signal; second spaceborne SAR is controlled, according to pulse width and starting time of second phase synchronization signal, to transmit second phase synchronization signal to first spaceborne SAR; compensation phase is determined according to peak phases of first and second phase synchronization signals received by second and first spaceborne SARs respectively; and phase synchronization compensation is performed, according to compensation phase, on radar signals received by first spaceborne SAR and second spaceborne SAR.
