Co-Prime Sensor Array Signal Processing

Abstract

We designed novel algorithms for various co-prime array signal processing problems. We developed new direction-of-arrival (DOA) estimators for wideband and distributed sources. We proposed a new tensor-based model for both electromagnetic and acoustic vector-sensor arrays. We developed high-resolution DOA estimators for off-grid sources using sparse modeling. We developed new approaches to calibrate sensor gain and phase errors. We conducted a comprehensive statistical performance analysis of coarray-based MUSIC, and analyzed the Cramer-Rao Bound for co-prime arrays. We investigated the statistical performance of co-prime arrays in the presence of sensor location errors.
