摘　　要：无线通信距离试验用于检验武器系统信息传输的能力,受试验场地的地形环境、电磁环境、装备状态等多种因素影响,无线通信距离试验是信息化试验中涉及装备多、规模大,组织困难的一项试验。根据无线数据传输成功率主要取决于信噪比的特点,推导出通信距离与电磁背景噪声的关系,通过在屏蔽室内测试装备全系统工作时的电磁背景强度,建立了可快速评估武器装备的最大通信距离的方法,省略了通信场地的选择。通过通信距离测试,证明了采用该方法评估武器系统的超短波通信距离的正确性。该方法可快速评估武器系统的超短波通信距离,减少了测试时间、降低了试验成本,避免了环境中电磁场对装备通信的影响。The wireless communication distance experiment is used for examining the information transmission ability of a weapon system.Affected by factors such as the test site′s terrain,electromagnetic environment and equipment conditions etc,the wireless communication distance experiment is an information-based experiment that involves many pieces of equipment,and is large in terms of its scale and difficult to organize.As the success rate of wireless data transmission is mainly decided by the signal-to-noise ratio,the relation between communication distance and electromagnetic background noise was deduced.By measuring the electromagnetic background intensity in the shield room when the whole system was working,a method that can quickly estimate the biggest communication distance of weapons was put forward,and the choice of communication site was ignored.Through the communication distance test,the method for estimating the VHF radio communication distance of weapon systems was verified.The method can quickly estimate VHF radio communication distance,reduce measurement time,lower test cost and avoid adverse effects of electromagnetic fields in the test environmentonweapon communication.
