摘要

摘要: 雷达及其对抗技术在雷达系统发展道路上相互促进，不断进步。近年来，外辐射源雷达凭借其优异的性能受到了国内外研究机构的广泛关注，相关技术得到飞速发展，部分设备已投入使用，但针对该新型雷达的干扰技术研究较少。该文基于辐射源信号结构，分析其信号组成，提出了一种基于信号结构特点的外辐射源雷达干扰方法。以数字广播电视外辐射源雷达为例，结合外辐射源雷达干扰模型，在所提方法下，干扰信号将在距离多普勒谱上形成干扰峰或干扰条带，可有效遮蔽目标，并形成虚假航迹，实现了对外辐射源雷达的干扰目的。仿真结果表明了干扰信号的特性和对目标干扰的有效性，为所提干扰方法在外辐射源雷达中的实际应用奠定基础。所提方法不仅适用于国内外数字广播电视外辐射源雷达，同时可扩展应用于其他类型的外辐射源雷达。

Abstract: Radar and its countermeasure technology promote each other and make continuous progress in the development of radar system. Recently, passive radar systems have received extensive attention by research institutes at home and abroad owing to their excellent performance. Moreover, the relevant technologies have been developed rapidly with some equipment being placed into operation. However, there is a lack of research on the jamming technology for this new-type radar. Here, we provide an analysis of the signal component based on the structure of radiation source signal. Next, we propose a passive radar jamming method based on the characteristic of signal structure, taking digital broadcasting television-based passive radar as an example. In the proposed passive radar jamming model, the jamming signal produces an interference peak or interference band in the range-Doppler map. These interference peaks or bands effectively mask the target and lead to a false track, thereby achieving the goal of jamming the passive radar system. Both the characteristics of the jamming signal and the effectiveness of the jamming method are verified by the simulation results. Moreover, the results presented here establish the foundation for practical application of a passive radar jamming signal. The proposed method could be applied into both the digital broadcasting television-based passive radar at home and abroad as well as other types of passive radar.
