Development of a high precision timing and control unit for Synthetic Aperture Radar

This paper discusses the design and development of an Field Programmable Gate Array (FPGA) based timing and control unit for high resolution Unmanned Aerial Vehicle (UAV) Synthetic Aperture Radar (SAR). The unit controls sub modules of SAR such as the timing of the chirp generator, the data acquisition module, the motion compensation module and any other modules that requires a control signal. The control signal supplied can be in the form of a signal window or a trigger pulse.
