Estimation of Power Spectra from Data Containing Recurring Pulses,

Abstract

There are many physical sources that generate recurring pulses. Rotating fans and propellers are two examples. The objective of this paper is to present a signal processing methodology to extract recurring pulses from data. the method relies on obtaining discrete frequency components over a band or discrete temporal components over a time interval. It is shown that the results for the time and frequency domains are duals of each other. These ideas are then generalized to the spatial domain by including an array of sensors. It is shown that the time-spatial domain and the frequency-wavenumber domain are also duals of each other.
