Abstract :
We describe a fully-electronic system for compressing and/or reversing arbitrarily-shaped waveforms in the time-domain using the principles of temporal imaging. The system accepts a arbitrary time-windowed broadband input and outputs a chirped waveform with the same envelope but compressed and/or reversed in time. We present a demonstration of a 3X time-compression and a basic time-reversal on a simple waveform and discuss the challenges and limitations of the proposed technique.
