在这个项目中，将为航空、通信和测量技术中的各种应用开发无线电干扰的基本新分析方法。本项目的重点是基于单个应用的误差量评估，这取决于干扰类型和动态接收器属性，例如积分时间。关于干扰的类型，特别是在具有移动的汽车或旋转的风力涡轮机的场景中存在的动态传播信道被调查。为了获得关于动态干扰和动态传播环境的基本结论，考虑了具有不同载波频率、调制方案、传播环境和干扰机制的各种应用。为此，使用任意波形发生器和软件定义的无线电在改变相关操作参数的情况下进行测量。此外，执行接收器架构、动态传播信道和误差量的特定于应用的评估的数学建模。此外，对于新的数学模型，还将开发误差量如何叠加的新方法，以求出误差概率。特别是，这是目前有关风力涡轮机对导航系统甚高频全向无线电距离(VOR)的影响、雷达探测概率和移动通信技术中关键性能参数的相关话题。

In this project fundamental new analysis methods for radio interference will be developed for a variety of applications in aviation, communication and measurement technology. The focus of this project is an individual application based assessment of error quantities, which depend both on the type of interference and dynamic receiver properties, e.g. the integration time. Referring to the type of interference, in particular dynamic propagation channels are investigated as present in scenarios with moving cars or rotating wind turbines. In order to obtain fundamental conclusions on dynamic interferences and dynamic propagation environments, a variety of applications is considered with different carrier frequencies, modulation schemes, propagation environments, and interference mechanisms. For this, measurements are done with arbitrary waveform generators and software defined radios under variation of relevant operating parameters. Additionally, a mathematical modeling of receiver architectures, dynamic propagation channels and the application specific assessment of error quantities is performed. Moreover, with respect to new mathematical models, new methods how error quantities superpose are to be developed also deriving error probabilities. In particular, this is currently a relevant topic regarding the influence of wind turbines on the navigation systems VHF omni direction radio range (VOR), detection probabilities with radar and key performance parameters in mobile communication technology.
