某型着陆引导雷达干扰技术研究

Study on the Jamming Technology in a Precise Approaching Radar

某型着陆引导雷达能在复杂气象条件下引导飞机着陆,在国内外军事上有广泛的应用;研究对其干扰技术,是导航对抗研究的一个重要方面;文中立足于导航对抗这一新的研究领域,提出了对某型着陆引导雷达干扰技术的研究;总结分析某型着陆引导雷达的系统特点,研究了对其干扰策略,重点研究了基于DFRM的距离—速度同步假目标欺骗干扰的方法,建立了干扰信号模型,并进行了仿真分析;仿真表明,这种假目标欺骗干扰的方法对某型导航雷达有较好的干扰效果。

A precise aproaching radar can be used for planes landing guidance in complicate weather condition, and has been used in mili- tary all over the world. Studies on the iamming technology against it become an important direction of navigation counter measure studying. This paper produces methods against this radar based on avigation counter measure studying. Firstly analyzes its system characteristics, then discusses the jamming technology, especially, the deception jamming technology with distance--speed in--phase based on DFRM and establishes the jamming signal model. Simulation and analysis shows that the proposed deceptional iamming technology is effective for jam- ming this kind of navigation radar.
