Abstract
A system for receiving signals from an array antenna that includes a first number of antenna elements, including an orthogonal signals generator module configured to generate the first number of orthogonal signals. Plurality of multipliers configured to receive array antenna element analog signals and the first number of orthogonal signals and generate a corresponding multiplied analog signal, giving rise to a first number of multiplied analog signals. A second number of summation modules configured to receive the first number of multiplied analog signals from the multipliers and generate a second number of summed analog signals. A second number of analog to digital converters configured to receive the summed analog signals and generate the second number of summed digital signals. The summed digital signals are capable of being fed to a digital processor for generating a processed signal of the array antenna, wherein the second number falls in the range of 1 to less than the first number.
