摘要
为了研究自适应调零下GPS干扰部署运用和效能评估问题,首先分析了传统GPS干扰典型运用方案,然后在噪声干扰及功率取大的调零策略前提下,提出了自适应调零下联合干扰压制区的建模方法。对全向干扰、定向干扰下的压制区进行了仿真分析,最后给出了GPS干扰效能评估指标及仿真结论。分析结果表明,自适应调零下的联合干扰压制区具备离散性、涌现性特点,干扰源的数量比作用距离更加重要,在目标预计出现的方向应尽可能垂直分开部署。
In order to research effectiveness evaluation and deployment of GPS jamming on adaptive nulling,the typical application scheme of traditional jamming is analyzed first.Then the modeling method of adaptive nulling joint jamming suppression zone is proposed under the premise of noise interference and zero setting strategy with higher power.The simulation examples of suppression zone under omnidirectional and directional jamming are analyzed,and the evaluation indexes of jamming efficiency and simulation conclusions are given.The analysis results show that the jamming suppression zone with adaptive subzero adjustment has the characteristics of discrete and emergence.The number of jamming sources is more important than the jamming range,and the jammer should be separate deployed as perpendicular to the direction of the expected target as possible.
