在抗干扰仿真系统中,需要建立不同的干扰模型来测试系统的性能。自回归(AR)干扰模型是一种使用非常广泛的干扰模型。在深入分析自回归AR干扰模型的特性、分析方法和参数求解算法的基础上,提出了一种功率和带宽等参数可变AR干扰建模的方法,通过对AR模型带宽、功率的控制和调整,建立不同特性的干扰,以达到对抗干扰仿真系统的测试。仿真实验结果说明,该方法简单,有效,使系统性能检测的实现更加灵活,在实际的工程中能够得到广泛的应用。
In the anti-jamming simulation system, different interference models need to be set up to test the performance of the system. Autoregressive (AR) interference models are a very widely used interference model. On the basis of deeply analyzing the characteristic, analysis method and parameter solving algorithm of autoregressive AR interference model, a variable AR interference modeling method such as power and bandwidth is proposed. Through the control and adjustment of AR model bandwidth and power , The establishment of different characteristics of the interference in order to achieve anti-interference simulation system testing. The simulation results show that this method is simple and effective, and it can make the system performance testing more flexible and can be widely used in practical engineering.
