Extraction of Resonant Modes from Scattered Noisy Data

This paper presents a technique that combines Prony’s original approach together with the high resolution eigenstructure based methods to estimate resonant modes from scattered noisy data. The problem is equivalent to obtaining best rational approximations that fit the actual measurements in a least square sense.
