Abstract :
In this research a universal, flexible, and compact processing unit with a time precision of about 30 ps is being designed and satisfactorily tested using the FPGA technology as a first step to implement the processing unit in a more compact fashion utilizing an ASIC technology. The work is being designed to replace the traditional expensive sampling method, which is used in most of the pulses radar application as core of the processing unit. The unit has been designed, implemented and tested on a LIDAR, which was accommodating a sampling oscilloscope to perform the signal processing. This processing unit could be considered as a low cost time-to-digital converter module.
