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.

It is required to plan the best route for the military UAV when carrying out accompanying penetration assignment, and the restraints of threat and arm performance should be considered seriously. An improved ant colony algorithm is proposed. Firstly, the threat effect is imported to correct the calculation of transfer visibility factor. The transfer probability is influenced sequentially and the entire security of the route is improved. Then, the pheromone is increased around the target node in reason to reduce the searching space and obtain the optimum route faster. The simulation results show the feasibility of the route planning method finally. The optimum routes are generated by weight change in transfer visibility factor calculation and can satisfy the commander needs for different backgrounds and tasks.
