Optical Direction-Finding Based on Silicon Photonic Integrated Circuits
Journal of Lightwave Technology, 2023In this paper, a high accuracy direction-finding (DF) system based on silicon photonic integrated circuits (PIC) is proposed. The accurate direction of a target can be determined by its position in the reconstructed image obtained by spatial frequency ...

Antiambiguity Direction Finding by Harmonics' Amplitudes With Two-Element Time-Modulated Array
IEEE Antennas and Wireless Propagation LettersA novel antiambiguity method is proposed to eliminate the mirror-image ambiguity generated in direction finding (DF) with the two-element time-modulated array based simply on harmonic amplitude. When the time delay of the two modulation sequences and the

Shipborne HFSWR Direction-Finding Method for Target Detection Based on Correction Matrix
IEEE Geoscience and Remote Sensing LettersBecause of the influence of various factors, such as platform motion, antenna error, clutter, and noise interference, the direction finding (DF) of targets using shipborne high-frequency surface wave radar (HFSWR) becomes extremely difficult, which poses

Direction Finding Method for Fast Beam Alignment in Wireless Communication Systems
Information and Communication Technology Convergence, 2023This paper proposes a simple direction finding (DF) method which aims to realize efficient beam management in mm-wave and THz frequency-band communications where a beamforming is essential. In the proposed method based on the DF built by the synthesis of

Practical Considerations of a Multi-Port Leaky-Wave Antenna Array for Direction Finding
European Conference on Antennas and PropagationAn array of multi-port leaky-wave antennas (LWAs) for direction finding (DF) in the X-band is proposed based on a printed double-stub configuration and analyzed in terms of practical considerations of range and detector sensitivity.
