摘要

This paper develops a new transmit beamforming for an integrated mechanical and elec-trical scanning dual-function radar-communication (DFRC) system. Differing from the related some works using beampattern sidelobe level to communication, we exploit the fact that transmit beam-forming weight vector uk in direction θ and weight vector uk? in direction ?θ can achieve the sameuk spatial power distribution, and formulate a new transmit beamforming vector design problem ac-counting for some extra sidelobe level constraints. By doing so, the number of the transmit beam-forming weight vectors and the computing demand in the multi-user communication (MUC) scen-ario can be reduced. Finally, the numerical examples are designed to verify the effectiveness of the proposed design strategy in comparison with the existing method.
