认知电磁环境适应系统在半实物软件平台的实现

Implementation of Cognitive Electromagnetic Environment Adaptation System in the Loop Software Platform

针对目前提高用频设备复杂电磁环境适应能力方法的不足,出于抑制交、互调等非线性失真干扰的目的,将正在蓬勃发展的人工智能方法适当地引入设备电磁防护领域,提出了认知电磁环境适应这一概念。认知电磁环境适应,立足于用频设备电磁环境效应和机理分析,以人工智能学习方法为途径,以软件化的设备为平台,以解决传统电磁兼容与防护方法的不完备、实时性差、无法适应复杂电磁环境等问题为目的。利用MATLAB仿真和现场可编程门阵列组成完整的认知电磁环境适应系统,建立起一个半实物的软件平台,验证了这新方法的可行性。

In view of the shortcomings of current methods to improve the adaptability of frequency equipment to complex electromagnetic environment, for the purpose of restraining nonlinear distortion interference such as cross modulation and intermodulation, the booming artificial intelligence method is appropriately introduced into the field of equipment electromagnetic protection, and the concept of cognitive electromagnetic environment adaptation is proposed. Cognitive electromagnetic environment adaptation is based on the analysis of electromagnetic environment effect and mechanism of frequency equipment, takes artificial intelligence learning method as the way and software equipment as the platform, and aims to solve the problems of incomplete, poor real-time performance and inability to adapt to complex electromagnetic environment of traditional electromagnetic compatibility and protection methods. A complete cognitive electromagnetic environment adaptation system is composed of MATLAB simulation and field programmable gate array, and a hardware in the loop software platform is established to verify the feasibility of this new method.
