Coherent Processing Across Multiple Staggered Pulse Repetition Interval (PRI) Dwells in Radar

Abstract

This report addresses the development of a methodology for dealing with staggered PRI coherent dwells in radar through the application of multirate signal analysis. The performance of multiple PRF systems is discussed along with the discussion of a number of techniques to obtain a spectrum from nonuniformly sampled data. The methods described include: Interpolating in spatial domain by polynomials; Chinese remainder theorem and the clustering algorithm; Least squares method; Multi-resolution analysis; Iterative method; Orthogonal Polynomial Expansions; and Estimation from the Analog Frequency. The report closes out with a comparison of various methods and a Conclusions section.
