实施转发式GNSS欺骗干扰的选星方法研究
|
摘要
在现代电子战的背景下,转发式GNSS欺骗干扰已经成为一种重要的干扰方式,通过研究实施转发式GNSS欺骗干扰的选星方法,可以提高转发式欺骗干扰的干扰能力.基于转发式欺骗干扰的实现原理,提出了一种基于常用GNSS定位选星方法和卫星对位置精度因子(position dilution of precision,PDOP)的贡献值选择被转发卫星的选星方法,基于利用最小二乘算法的伪距绝对定位方法进行仿真,模拟了接收机在静态和动态条件下受到单颗卫星转发式欺骗干扰的情况.仿真结果表明,本文提出的被转发卫星选择算法分别有87.42%和100%的概率给出理论上最优的选星结果.
In modern electronic warfare, the GNSS repeater deception jamming has been an important method of jamming. With the research on satellite selection algorithm of GNSS repeater deception jamming, the jamming ability of repeater deception jamming can be improved. A satellite selection algorithm was proposed based on the satellite selection method of common GNSS positioning and PDOP contribution of single satellite. The simulations were carried out based on the pseudorange single positioning method with the least-squares algorithm, under the static and dynamic conditions respectively. And the receiver attacked by repeater deception jamming with single satellite was simulated under both static and dynamic conditions. The simulation results show that the satellite selection algorithm for repeater deception jamming proposed in this paper can provide the theoretically optimal star selection result with high probability.
