Parallel Factor Analysis in Sensor Array Processing
- IEEE TRANS. SIGNAL PROCESSING
, 2000
"... This paper links multiple invariance sensor array processing (MI-SAP) to parallel factor (PARAFAC) analysis, which is a tool rooted in psychometrics and chemometrics. PARAFAC is a common name for low-rank decomposition of three- and higher way arrays. This link facilitates the derivation of power ..."
