The synchronous control of multi-motors is essential in multi-axis motion control system. Compared to single-axis tracking error, the synchronization error, responsible for final machining accuracy, is more important. There is correlation among axes, which can lead to mismatch in speed and position among axes when different load disturbances or other factors of each axis emerge. That means appropriate...
Doppler Centroid estimation is a crucial problem in Synthetic Aperture Radar(SAR). In Bistatic SAR (BiSAR) phase synchronization error and Doppler phase have nearly the same form; Doppler centroid can not be estimated in traditional way. A Doppler centroid estimation method is proposed for Space-Surface BiSAR system through phase-cancellation of Dual-channel direct signal. Through phase cancellation,...
Signal model has great significance to time and phase synchronization research in a bistatic radar. In prevenient research, time synchronization and phase synchronization are investigated separately and their coupling relation has not been investigated. This paper introduces a bistatic radar signal model according to system's composition and operation procedure. From the radar operation principle,...
