PROJECT TITLE :

Ultra-wideband instantaneous frequency estimation

ABSTRACT:

Determining the instantaneous frequency of a proof is needed for many applications starting from radio astronomy to defense applications. Unfortunately, the scan rate is usually too long over a wideband spectrum compared to the time scale of signals of interest. We tend to gift an on the spot frequency measurement receiver, which permits for simultaneous measurement of multiple frequencies and amplitudes across an ultra-wide instantaneous bandwidth. Powered by the photonic time stretch A/D converter, the high effective sampling throughput of the system provides high temporal resolution and improvement of frequency and amplitude estimation capability through advanced Signal Processing. This flexible system has adjustable instantaneous bandwidth and frequency resolution, an ultrafast sweep time, and reduced hardware complexity compared to different instantaneous frequency measurement systems.
