For the case of the guidance handover for interception beyond visual range of the semi-active ship-air missile by ship-ship coordination,the scenario of ship-ship collaborative guidance was set,and based on the analyses on the operative flow,two handover methods were firstly presented by combining the program trajectory solution and mobile communication switching technology,which are the direct switch and the interactive switch.And the feasibility of the designed methods was demonstrated,the key technology and implementation approach were put forward.Finally the advantages and disadvantages of the handover methods were analyzed.
