摘要：
A detailed analysis of the relationship between the steered beam response and the original one is provided for wideband beamforming based on a uniform linear array. It is shown that after adding steering delays to the originally received wideband array signals, the main beam will be shifted to the desired directions. However, for the sidelobe region, for one side, it is shifted out of the visible area; for the other side, it is not a simple shifted-back of those shifted out, but exhibits a very complicated pattern.
