摘　　要：研究水下军事通信中短距离通信优化方法，提高通信服务质量。在水下通信过程中，由于短距离通信信号可辐射功率小，很容易受到反馈回波的影响，造成信号的可分辨性下降。传统的通信方法以10～100m之间呈现片状网络结构通信，在应用到水下短距离通信中，回波干扰下信号分辨率的降低会大幅影响通信效率，造成通信中断等弊端。为解决上述问题，提出基于加权组播树算法的水下军事通信中短距离通信优化方法。根据水体运动情况，获取随机线性函数，得到军事通信状态方程，并进行求解，完成军事通信信号的抗干扰处理。根据加权组播因子，建立加权组播树，实现水下军事通信中短距离通信优化。实验结果表明，利用改进算法进行水下军事通信中短距离通信优化处理，可以极大地提高通信效率，降低误码率，满足水下军事通信的需求。Underwater short distance communication in military communication optimization method is presented, which can improve the quality of service. In the process of underwater communication, short distance communication signals is radiated with small power, which is easily affected by the feedback of the echo. It results in the loss of sig- nal distinguish. The traditional communication method in 10 ~ 100 m between lamellar network communication structure, when applied to underwater short distance communication, under the disturbance of echo signal resolution reduce dramatically affect communication efficiency, will create the disadvantages such as communication interrupt. Therefore, underwater short distance communication optimization method is presented based on weighted muhicast tree algorithm in military communication. According to the water body movements, the stochastic linear function is obtained, and the military communication state equation is derived and solved, to complete the military anti-disturb- ance communication signal processing. Based on the weighted factor of multicast, weighted muhicast tree, underwater short distance communication is optimized in military communication. The experimental results show that the improved algorithm for underwater short distance communication in military communication optimization can greatly improve the efficiency of communication, reduce the bit error rate, and meet the requirements of underwater military communica- tions.
