A method of processing signals received and transmitted between a satellite and sub-arrays of an antenna array. The satellite emits an analog signal received by the sub-arrays, each sub-array in turn produces a corresponding output. The array's total output is approximated by designating one of the sub-array's output as a reference output, and digitally forming a series of beams that consist of the reference output and permutations of the other sub-array outputs with either no time delay or with a time delay applied. A high power beam from the series is selected for cross correlation with each sub-array output to determine the signal's relative arrival time at each sub-array. Each sub-array output is time delayed based on the signal arrival time at that sub-array. The time delayed outputs are combined to form a high gain beam.
