基于计算机仿真的短波通信网覆盖分析

摘要

Short wave communication network coverage analysis is critical in prediction and assessment of communication situation and is important for communication commander to obtain effective decision support information. Based on antenna three-dimensional space gain calculation and space propagation calculation theory, a mathematical model is built for short wave communication network coverage analysis. NEC and ICEPAC procedures are used; digital acquisition of parameters is performed; computer simulation is performed ; and the mathematical model is implemented using computer. The simulation results with actual receiving conditions are analyzed and discussed in detail. Research results can provide strong basis for design optimization of short-wave communication station, communication network planning and communication sector decision support, and macroscopic management.%短波通信网覆盖分析是预测和评估通信态势的重点和难点,是为通信指挥员提供有效决策支持信息的前提。以天线三维空间增益计算和空间电波传播计算理论为基础,构建了进行短波通信网覆盖分析的数学模型;利用NEC和ICEPAC程序,并通过数字化获取参数,进行了计算机仿真,给出了数学模型的计算机实现。对仿真结果结合实际收信条件作了较为详细的分析和讨论。研究结果为短波通信台站最优化设计、通信网络规划及通信指挥部门的决策支持、宏观管理提供了有力依据。
