Robust Co-Prime Sensing with Underwater Inflatable Passive Sonar Arrays

Abstract

The research objective is to support development of an underwater inflatable co-prime sonar array (UICSA) by devising associated signal processing capabilities. The focus of our studies has been in the following areas: (i) Generalized design of optimal autocorrelation combining in the mean-square sense for direction finding; (ii) Design of iterative Fourier methods for exploitation of full degrees-of-freedom indirection-of-arrival (DOA) estimation with co-prime arrays; (iii) DOA estimation in the presence of unknown correlated ambient noise; and (iv) Narrowband and multi-frequency co-prime processing for validating the DOA estimation performance of the devised UICSA prototype.
