Using correlation characteristics of Zadoff-Chu sequence to measure DOA and TOA by synthetic aperture antennas

This paper simplifies the measurement of the DOA and TOA of widely separated synthetic aperture (SA) antennas. This paper proposes a method based on the Zadoff-Chu sequence to achieve DOA and TOA measurements with the high angular resolution even if widely separated. The performance of the proposed method is confirmed by tests in an anechoic chamber.
