导弹尾焰等离子体对遥测信号影响建模方法
|
摘要
针对遥测信号因尾焰干扰发生强烈衰减而缺乏准确理论计算模型的问题,提出了导弹尾焰等离子体对遥测信号影响的数学和仿真建模方法。该方法计算了等离子体密度、厚度和入射电磁波频率等电磁特性参数对遥测电磁波信号传输性能的影响,并搭建了FDTD Solution软件仿真模型。仿真验证结果表明,导弹试验前通过该数学模型和仿真模型的计算,能够准确得出遥测信号受影响程度以及推算全弹道信号遮挡区域,为遥测设备优化布站解决信号失锁丢失问题提供技术支持。
Aiming at the problem of lack of accurate theoretical calculation models, the mathematical and simulation models of the impact of missile plume plasma on telemetry signal was proposed in this paper. The effect of the plasma density, the thickness and the electromagnetic frequency were discussed, and the simulation model of FDTD solution was built. The research indicates that the impact of telemetry signal and full ballistic signal blind zone could be accurate calculation, the result could provide the appropriate project of station location to solve the signal loss question.
