More Information
Summary:The invention discloses a satellite-borne low-frequency electrically small broadband three-axis vector array and a signal direction and polarization estimation method, and the three-axis vector array comprises three low-frequency electrically small dipole broadband active antenna units, a three-channel direct data collection unit and a signal comprehensive processing unit. The three low-frequency electrically small dipole broadband active antenna units are located in different axial directions, are mutually orthogonal in pairs, share the antenna phase center, and are respectively used for receiving and processing space detection signals in different axial directions; the three-channel direct data acquisition unit is used for performing analog-to-digital conversion processing on the processed three-channel space detection signals; and the signal comprehensive processing unit is used for processing the three-channel digital signal after analog-to-digital conversion to obtain the frequency spectrum, direction an
