Introduction

Hangjian Li is a prominent inventor based in Beijing, China. He has made significant contributions to the field of radar technology, particularly in phase synchronization methods. His work has implications for various applications in synthetic aperture radar systems.

Latest Patents

Hangjian Li holds a patent for a "Method and device for non-interrupted phase synchronization scheme for bistatic synthetic aperture radar." This innovative method involves determining the pulse widths of first and second phase synchronization signals, as well as the starting time of their transmission. The process ensures that the starting time is strategically located between two successive moments when radar signals are transmitted. The first spaceborne synthetic aperture radar (SAR) transmits the first phase synchronization signal to the second spaceborne SAR, while the second spaceborne SAR transmits the second phase synchronization signal back to the first. The compensation phase is then determined based on the peak phases of the received signals, allowing for effective phase synchronization compensation on the radar signals.
