Millimeter wave (mmWave) communications of unmanned aerial vehicles (UAVs) have drawn dramatic attentions for its flexibility on a variety applications. Recently, channel tracking base the spatial features has been proposed to solve problem beam misalignments due UAV navigation. However, unstable pointing caused by non-ideal environment may impact performance mmWave systems significantly. In this paper, an improved beamforming method is presented overcome shortcoming. Firstly, effect deviation analyzed through establishment equivalent data rate. Then, combining quantification angle and orthogonal matching pursuit (OMP) algorithm, optimized corresponding obtained. Simulation results show that approach can effectively improve spectral efficiency without improving complexity when unstable.
