摘　　要：具有定向收发能力的武器协同数据链,在时分半双工方式下完成实时信息共享对于系统效能提升有重要意义。结合理论分析,给出了既定通信模式下完成信息共享所需的最少时隙数,以此作为最优条件设计了相应的调度方案和计算机算法。计算机算法采用嵌套结构,易于实现。通过仿真从算法复杂度、实时性以及节点负载均衡等方面进行了分析。结果表明,算法能使共享所需时隙接近理论最优值,且性能优于传统的信息共享方法。The weapon collaborative data link with directional transmission and reception capability to realize real-time information sharing in time division and half-duplex mode is of great significance for system performance improvement.Combined with theoretical analysis,the minimum number of time slots required for information sharing in a given communication mode is given,and the corresponding scheduling scheme and computer algorithm are designed as optimal conditions.Computer algorithms use a nested structure that is easy to implement.The simulation is analyzed from the aspects of algorithm complexity,real-time ability and node load balancing.The results indicate that the algorithm can make the shared time slots close to the theoretical optimal value,and the performance is better than the traditional information sharing method.
