Abstract
An active electronically steerable receive antenna may comprise an antenna array that includes multiple receive antenna elements. Reflected radar signals may be received at the receive antenna elements, and received signals may be obtained from the receive antenna elements. The received signals may be processed via at least frequency down-conversion, analog-to-digital conversion, generation of digital signals, and alignment of the received signals or the digital signals for a predetermined angle of incidence. Multiple signals including a sum beamforming signal and a product beamforming may be multiplied to determine a beamformed signal. The sum beamforming signal and the product beamforming signal may be respectively determined by summing or multiplying at least two of the digital signals. The product beamforming signal may be a grating lobe suppression signal that suppresses grating lobes of the sum beamforming signal when multiplied with the sum beamforming signal.
