CONFORMITY EVALUATION METHOD OF RADOME FOR 3 DIMENSIONAL INTERFEROMETRIC ARRAY BY PHASE DIFFERENCE ERROR ESTIMATION

摘要

PURPOSE: A compatibility judging method of a radome for a 3D interferometer array is provided to judge the compatibility of the radome used for the 3D interferometer array by comparing a distance between the phase differences in a result which performed an Euler angular transformation with the phase difference that penetrated the radome for each separate distance. CONSTITUTION: For a plurality of receiving antenna, the phase differences between two of the receiving antennas facing each other is obtained for each antenna separation distance(S100). From the calculated phase differences, a phase difference error between two of the receiving antennas facing each other for each separate distance is calculated(S200). For the phase difference for each separate distance, the Euler angular transformation is performed(S300). By the Euler angular transformation, the distance of the phase difference error in an axis-transformed space is calculated(S400).
