Comparison of two beam-books; (left) phase shifters set to corner settings (maximum power), (right) generated with the proposed algorithm (K = 10, N = 1, M = 1, SLL <− 9 dBc, flattened amplitude). The signal chain is saturated. a Mainlobe peak power when phase shifters are set to corner settings. b Mainlobe peak power when phase shifters are set using the proposed algorithm. c SLL when phase shifters are set to corner settings. d SLL when phase shifters are set using the proposed algorithm. e Step size with adjacent beam when phase shifters are set to corner settings. f Step size with adjacent beam when phase shifters are set using the proposed algorithm. g −3 dB beamwidth when phase shifters are set to corner settings. h −3 dB beamwidth when phase shifters are set using the proposed algorithm
