Abstract: In the array signal receiving, the different time delay of the desired signal is received by the array antenna because of the signal multipath effect. So high accuracy beamforming with time delay signals is an intractable problem in the signal processing. In this paper, a beamforming algorithm considering the time delay signal is proposed. The time delay estimation value is calculated by the wavelet algorithm at first. And then the time delay estimate is compared with the prestored time delay value to choose the desired signal direction. The spatial multi-beam with approximate desired signal direction is optimized by iteration to implement overall adaptive beam in space. The simulation results show the effectiveness of the improved algorithm.
