Summary:
A distributed array with a very large aperture can form a very narrow beam and has very high gain. A radar system with such a distributed array thus provides high resolution and long-distance detection. We study the Capon’s beam former applied to a non-uniformly arranged distributed array to attain high resolution and long distance detection. It was found that the non-uniform arrangement can suppress the spatial correlation between the main lobe and the grating lobes. Accordingly, the Capon’s beam former even can suppress grating lobes. Experiment results on antenna patterns and the null beam gain show that the grating lobes are successfully suppressed by the Capon’s beam former.
