摘要

There are two main methods for solving interferometer phase difference ambiguity in systems of passive localization by airborne single position. One is based on combination of long baseline and short baseline, and the other is based on remainder theorem of bi-baseline system. Because the algorithm based on remainder theorem of bi-baseline system just requires that the lengths of baselines are relatively prime and it is unnecessary to confine the lowest limit of baseline length less than half a wavelength, and the number of antennas are moderate, so it is easy to carry out. The principles and the realization procedure are discussed, and the precision request for measurement of the additive phase interferometer to solve ambiguity correctly is analyzed theoretically. Then the validity of the algorithm is proved by simulation. So this algorithm as the theory basis for engineering realization of passive localization by airborne single position is effective.
