Abstract

Bistatic synthetic aperture radar (BiSAR) and multistatic (MuSAR) systems with a separated transmitter and receiver have been widely used for remote sensing. However, frequency deviation among different oscillators will cause a modulated phase error on the echo signal. Therefore, phase synchronization is one of the most critical problems to be addressed in BiSAR/MuSAR systems. In this article, we review synchronization techniques, which include synchronization by direct signal, synchronization by synchronization module, and synchronization by autonomous estimation. Furthermore, the future development of synchronization technology is prospected.

双基地和多基地合成孔径雷达的相位同步技术：考虑频率偏移

具有分离发射器和接收器的双基地合成孔径雷达（BiSAR）和多基地（MuSAR）系统已被广泛用于遥感。然而，不同振荡器之间的频率偏差将导致回波信号上的调制相位误差。因此，相位同步是BiSAR/MuSAR系统中需要解决的最关键的问题之一。在本文中，我们回顾了同步技术，包括直接信号同步、同步模块同步和自主估计同步。并对同步技术的未来发展进行了展望。
