Improved Ambiguity-Resolving for Virtual Baseline
Abstract: A novel phase
interferometer method based on virtual baseline is proposed for technical
difficulty in resolving angle ambiguity and antenna layout. In this method,
only two baselines are set to solve the problem of angle ambiguity. In high
noise areas, there are large numbers of outliers which lead to angle error in
the measured data, and a way to detect and eliminate the outliers is applied to
improve the effect of solving ambiguity. The simulation results show that the
improved method could effectively correct the error of fuzzy phase difference
and increase the probability of ambiguity-resolving. Duo to its simple
equipment and easy to implement, the proposed method might have certain guiding
significance to engineering application.
