摘要
在火炮通信系统的设计过程中,天线布局是影响无线通信距离的重要因素之一。通过对炮塔上超短波天线不同布局方案的分析,研究了天线安装在不同的倾斜角度与天线被其他设备遮挡的多种状态下,无线传输8 km处超短波电台接收功率的变化规律。利用Egli电磁波传播模型进行了理论分析,根据电波模型所涉及的影响电磁波传播的重要参数,计算出了一定距离条件下的超短波电台的接收功率和接收功率为-97 dBm条件下的无线通信距离,验证了天线布局对无线通信距离产生的影响。在此基础上,提出了天线布局设计的优选方案,进而为火炮通信天线的布局设计和应用提供参考。
In the design of artillery communication systems,antenna layout is one of the important factors that affect wireless communication distance.Through the analysis of different layout schemes of a VHF antenna on the turret,this paper studies the change law of received power of a VHF radio 8 km away through wireless transmission when the antenna is installed at different tilt angles and the antenna is blocked by other equipment.The Egli radio wave propagation model is used for theoretical analysis.According to the important parameters that affect the propagation of electromagnetic waves involved in the model.The received power of the VHF radio at a certain distance and the wireless communication distance when the received power is-97 dBm are calculated.On this basis,the optimization scheme of antenna layout design is proposed,which provides a reference for the layout design and application of artillery communication antenna.
