Abstract :
In this paper, a new method is presented to design robust low-sidelobe wideband constant beamwidth beamformer in time domain, which alleviates the effect caused by array mismatch errors and get lowly sidelobe level. Results of computer simulations for a twelve-element array demonstrate satisfactory performance of the proposed approach.
