“…Hence, in the phase interferometer algorithm, there is an inherent contradiction between the DF accuracy and the maximum unambiguous angle. To overcome this issue, multi-baseline configurations are typically adopted, including the use of long and short baselines, virtual baselines, and other disambiguation algorithms [18,19,[21][22][23]. In practical applications, the method of combining long and short baselines for VLF signals has specific limitations.…”

“…By analyzing the phase difference between any two received signals, the azimuth angle of the EM waves can be determined, thereby obtaining the direction of the radiation source. Due to the phase ambiguity in interferometers [17], researchers have conducted in-depth research over the years to resolve this ambiguity [18][19][20][21][22][23]. In the context of space-borne receivers, several researchers have proposed rotational baseline disambiguation methods based on the spinning motion of satellites [24,25].…”

This paper proposes a dynamic phase comparison algorithm for planar direction finding on a high-speed moving satellite radio receiver, treating the moving antenna as equivalent to single-baseline array antennas. Based on a phase interferometer algorithm, this algorithm adjusts the baseline length according to the frequency measurement module and the satellite’s high-speed motion to avoid phase ambiguity indirectly. By integrating the traditional amplitude comparison algorithm based on orthogonal dipole antennas, a dynamic fusion direction-finding method is proposed. Simulations demonstrate that this approach method not only covers a broader range of direction finding but also achieves higher accuracy, providing valuable insights for acquiring three-dimensional plasmagrams with space-borne plasma imagers.
