【Abstract】 The principle for phased-beam forming of Doppler log and mixing frequency and shifed-phase for numerical control attenuator is discussed in the paper. The way to form phased-beam by using attenuator is proposed. Experiments prove the feasibility of forming phased-beam by using attenuator.更多还原
