Co-Prime Frequency and Aperture Design for HF Surveillance, Wideband Radar Imaging, and Nonstationary Array Processing

Abstract

The research objectives are to develop novel co-prime sampling and array design strategies that achieve high-resolution estimation of spectral power distributions and signal direction-of-arrivals (DOAs), and their applications in various surveillance, radar imaging applications, and array processing. The focus of our studies has been in the following five areas: (i) Generalized co-prime array design; (ii) Wideband DOA estimation and radar sensing; (iii) Active sensing using co-prime arrays; (iv) Mutual coupling effect and mitigation; (v) Spectrum estimation based on co-prime sampling.
