摘要
为提高数据链的低被截获性能,文中提出了三种基于射频隐身的数据链功率控制方法。根据数据链系统是否进行功率控制信息交互,将功率控制方法分为了合作功率控制和非合作功率控制。在非合作功率控制模式下,通过对射频隐身性能参数的深入分析,又提出了基于位置关系和基于信号强度的功率控制方法。仿真结果表明,所提出的射频隐身功率控制方法与目前常见的数据链恒定功率辐射方法相比,在满足通信可靠性的前提下,消耗能量较少,具有较好的射频隐身性能,其中合作功率控制方法在能量消耗和功率控制精度上具有最优性能。
In order to increase the interception performance of the datalink, this paper proposes three power control methods based on RF stealth. Power control method is divided into cooperation and non-cooperation, according to the interaction of datalink. Through the depth analysis of RF stealth performance parameters, two methods are proposed which are based on the positional rela- tionships and the signal strength in non-cooperative power control mode. Compared with the constant radiation power method, the simulation results show that the three proposed methods consume less energy and have better performance of RF stealth. The coop- erative power control method has optimal performance in energy consumption and control precision.
