A kind of beam-scanning algorithm of variable polarization millimeter array antenna based on the phased array technology is put forward in this paper.The algorithm can be successfully applied to deal with beam directivities inconsistency of millimeter wave/infrared( MMW/IR ) multimode detector,it can keep electric axis and optical axis coincident.Accordingly,this method can decrease the data fusion difficulty and improve the accuracy of angle measurement.Simulation results show that variable polarization millimeter array antenna has flexible beam-scanning abibility within ±0.5° after the algorithm was adopted,simultaneously,antenna polarization purity is better than 20 dB within the half power beamwidth,sidelobe imbalance keeps high available and antenna gain of the sum beam is over 26.8 dB.
