Abstract: In recent times, digital beamforming with an analog-to-digital converter for a phased-array radar has attracted wide interest due to its stability and accuracy. Generally, to obtain a high gain, a phased array radar requires many antenna elements, which results in high cost and computing load. To mitigate these problems, subarraying, which divides the entire array elements into a few disjoint groups, is a good solution. In this paper, we propose a new design methodology for disjoint subarray configuration based on a modified Genetic algorithm and a new grouping rule to preserve the number of desired subarrays. The validity of the proposed algorithm is demonstrated through simulation.
