Abstract

The frequency hopping radio has been widely used for its anti-interference ability. However, in the installation, testing and evaluation of short-wave frequency hopping radio, a realistic time-varying electromagnetic environment support is lacking. Hence, it is important to construct the time-varying electromagnetic environment which the short-wave frequency-hopping radio may face. To solve this problem, this paper firstly finds out live kinds of signals commonly faced by the short-wave frequency-hopping radio and extracts their time-varying parameters by signal simulations with MATLAB. After that, a model based on the traversal is proposed, which accurately reconstructs the time-varying electromagnetic environment. Finally, this model is implemented on the FPGA, which could generate a feasible time-varying signal to represent the electromagnetic environment. This device may be useful for the installation, debugging, testing, evaluation and other tasks of short-wave frequency hopping radio.

一种基于fpga的时变电磁环境建模与生成方法

跳频无线电以其抗干扰能力得到了广泛的应用。然而，在短波跳频无线电的安装、测试和评估中，缺乏一个真实的时变电磁环境支持。因此，构建短波跳频无线电可能面临的时变电磁环境具有重要意义。为了解决这一问题，本文首先找出短波跳频无线电通常面临的实时信号种类，并利用MATLAB进行信号仿真，提取其时变参数。在此基础上，提出了一种基于遍历的模型，能够准确地重建时变电磁环境。最后，在FPGA上实现了该模型，该模型可以生成一个可行的时变信号来表示电磁环境。该装置可用于短波跳频无线电的安装、调试、测试、评估等工作。
