Abstract

Abstract

In order to adapt to various array layouts, a direction-finding method with arbitrary planar array interferometer based on mixed baselines is proposed. Firstly, based on the analysis of the mathematical model without phase ambiguity, the direction-finding method via the mixed baselines with arbitrary planar array interferometer is derived. Secondly, for the problem of phase ambiguity, a clustering method based on the improved direction function with normalization is proposed, and the selection method of the baseline pairs is given. Finally, numerical simulations are performed to verify the effectiveness of the proposed method on random arbitrary array, uniform circular array and semicircular array. This method does not restrict the lengths and the slopes of the two baselines in the selected baseline pair. The simulation results show that with the help of flexible selection of baseline pairs and the introduction of the improved direction function with normalization, the ambiguity resolution performance of the mixed baselines algorithm is better than the equal-length baselines algorithm and the stereo baselines algorithm.
