Kalman Filter Time Series Analysis of Gamma-Ray Data from NaI(T1) Detectors for the ND6620 Computer.

Abstract

The Kalman Filter technique is applied to time series gamma-ray data from NaI(T1) detectors. A set of standard spectra which contribute significantly to the data in the least-squares sense are first determined using regression analysis. The Kalman Filter computer program is then used to determine the time behavior for the intensities of the standards which contribute to the observed spectra. The program was written for the ND6620 computer in DEC RT-11 FORTRAN and is being transferred to the VAX 11/780. Keywords include: NaI detectors, Gamma-ray spectra, Time series analysis, Kalman filter.
