摘要
转发式欺骗通过增加人为延时使得伪距值发生变化,进而影响定位结果,是一种比较理想的干扰方式。为提高欺骗的准确性,通过构建转发式欺骗数学模型,分析了影响转发式欺骗定位的各种因素,计算了定位的几何精度因子(GDOP),并通过仿真得到了转发式欺骗在各误差源综合影响下的定位精度结果,为转发式欺骗的工程实现提供了一定的理论依据。
Repeater deception is an ideal way of jamming to make pseudo-range change through increasing the time-delay,thus affecting the positioning.In order to improve the accuracy of deception,various factors affecting the positioning are analyzed through describing mathematic model of repeater deception jamming,the Geometric Dilution of Precision（GDOP）is also calculated.The positioning result under the comprehensive influence of each error source is obtained by simulation,which provides a certain theoretical evidence for the project realization of repeater deception.
