摘要：

In this paper, an efficient beamforming technique is proposed where the Kaiser window is designed and applied to the uniform concentric circular arrays (UCCA) for sidelobe reduction. This technique is based on tapering the current amplitudes of the rings in the array, where all elements in an individual ring are weighted in amplitude by the same value. Based on establishing some mapping curves, this modified tapering window is optimized in its parameters to have the lowest possible sidelobe level that can be 45 dB below the main lobe level and these optimum weights are found to be function of the number of elements of the innermost ring and the number of rings in the array.
