In order to solve the problem of sampling remote UWB radar signals
a real-time sampling design plan based on 1Gsps ultra-speed sequences has been proposed
which uses a new method for reducing the frequencies in all databases with the input of 1ns in a dual-memory system structure.When demanding for improvement factor on an A-D dynamic range has come out
the principle of random sampling with combination of pS timing on the time axis is exposed to increase the realization of technology in 12 units of 5Gsps design methods for sampling systems.This method gives a very high practical value to the UWB radar signals processing
digital oscilloscopes
frequency spectrum analyzers
etc.
that exist among the theory and applications of high-speed digital oscilloscopes system designs.
