Abstract
To eliminate the complexity and the weight involved in the use of a Butler matrix, the present invention matrix antenna array uses a combination of processors and analog multipliers for weighting the signals, either to be transmitted or received, from the corresponding antenna element of the array. Since the analog multipliers are adaptable to operate in the microwave frequency, the control signals can be multiplied with the radar signal directly so that complexity of construction, bulkiness and heavy weight are eliminated from the matrix antenna array of the present invention.
