阵列式射频仿真系统中箔条运动模型研究

Research on Motion Model of Chaff Cloud in Radio Frequency Simulation System

箔条射频仿真是阵列式射频仿真系统的一项重要内容。目前对于箔条空中运动模型的研究还不够深入,无法满足射频仿真试验中箔条空间运动精确模拟要求。针对该问题展开阵列式射频仿真系统箔条空间运动模型研究,通过对射频阵列空间位置模拟原理及箔条空中运动规律的分析,构建出箔条空间运动模型并利用Matlab及VC进行仿真实现,最后根据该运动模型开发出能够用于仿真试验的箔条航迹模拟软件。试验结果表明,该模拟软件能够模拟产生阵列控制所需的大地坐标系下箔条弹空中运动航迹,对于提高箔条模拟逼真度及仿真试验置信度具有一定参考价值。

Chaffradio frequency simulation is an important content of Radio Frequency Simulation System. Currently, research of chaff motion model is not thorough and can not satisfy the requirement of accurate simulation. In order to solve the problem, chaff motion model was researched by analyzing position simulation principle of radio frequency simulation system and movement of chaff, and the motion model of chaff cloud was established and emulated with Matlab and VC. Finally, according to the model, the software which could produce simulation locus was developed. The experimental results demonstrate that the software can raise fidelity of the chaff simulation and confidence of simulation experiment.
