Query: EOVSA Implementation of a Spectral Kurtosis Correlator for Transient
  Detection and Classification   We describe in general terms the practical use in astronomy of a higher-order
statistical quantity called Spectral Kurtosis (SK), and describe the first
implementation of SK-enabled firmware in the F-engine (Fourier
transform-engine) of a digital FX correlator for Expanded Owens Valley Solar
Array (EOVSA). The development of the theory for SK is summarized, leading to
an expression for generalized SK that is applicable to both SK spectrometers
and those not specifically designed for SK. We also give the means for
computing both the SK estimator and thresholds for its application as a
discriminator of RFI contamination. Tests of the performance of EOVSA as an SK
spectrometer are shown to agree precisely with theoretical expectations, and
the methods for configuring the correlator for correct SK operation are
described.
