Abstract:
With the development of virtual test, the computation of the effect of different weather conditions on electromagnetic wave propagation is required in many simulation systems. Firstly, this paper presents a unique point of view for computing the electromagnetic wave attenuation ratio under different weather conditions by means of an independent electromagnetic wave propagation component that can be directly implemented in virtual test, and is easy to configure and easy to reuse. We present an analysis of the principles of electromagnetic wave propagation and the algorithms designed for realization of various propagation models within the electromagnetic wave propagation component. Secondly, this paper presents a use-case analysis and outlines the design of the component, verifies the developed models under various weather conditions, and obtains equivalent values as those obtained theoretically. Finally, we build a virtual test system, verify the system in different weather conditions, and again obtain equivalent values to those obtained theoretically. The algorithms in the electromagnetic wave propagation component are developed in the C language, which substantially improves the computational speed, and meets the real-time requirements of the virtual testing platform.

3)通过HIT-TENA体系结构构建了一个虚拟试验系统,通过典型天气下的多个虚拟试验,验证了本文开发的电磁波传输模型的有效性。

研究目的

虚拟试验技术是近年来一种新兴的试验技术,主要用于对武器装备进行复杂环境条件下的试验验证,评价其在复杂环境下的作战效能等。虚拟试验离不开虚拟环境以及相应的环境效应,本文针对一种常用的环境效应模型——电磁波传输效应模型展开研究。电磁波传输模型常用于雷达类的虚拟试验中。本文针对虚拟试验对模型实时性和通用性的要求,研究了电磁波传输模型的快速计算方法,并将其封装为具有独立功能的试验资源。

1)分析了典型天气下的电磁波传输模型,针对虚拟试验实时性的要求,针对每种模型提出了基于C语言的快速计算步骤;

2)利用UML建模语言,设计了运行于HIT-TENA平台上的具有通用性的电磁波传输资源;

3)利用一个雷达制导导弹攻击目标的虚拟试验验证了本文开发的电磁波传输资源有效性。

结果

1)通过跟理论模型的传输曲线进行对比,证明了本文开发的电磁波传输模型的计算精度;

2)通过一个虚拟试验验证了本文开发的电磁波传输效应资源在虚拟试验中的应用有效性。

结论

在本文中,我们针对晴天、雾天、雨天、雪天共4种典型天气下的电磁波传输展开研究,通过快速计算方法构建了满足虚拟试验实时性要求的电磁波传输模型。然后,开发了运行了HIT-TENA虚拟试验平台上的电磁波传输效应组件,该组件不但能计算不同天气条件下的电磁波能量衰减,而且在HIT-TENA平台下实现在其他试验系统中的重用。
