Estimating the magnitude square coherence spectrum

Abstract

Even though the Magnitude Square Coherence (MSC) spectrum is 
useful in a wide variety of applications, such as for instance 
SAR imagery, few methods exists for forming an accurate high-
resolution estimate of the spectrum. In this talk, we will 
provide a review of some recent work on data-adaptive spectral 
estimation techniques as well as exploit these techniques to 
formulate high-resolution estimates of the 1-D and 2-D MSC 
spectrum. We will further discuss ways to efficiently time-
update such estimates as additional data becomes available.
