为解决GPS/INS组合导航对抗难题,提出一种针对GPS/INS组合导航的曳引式拉偏干扰方法。通过干扰设备产生欺骗干扰信号,使GPS/INS组合中的GPS接收机输出与其实际位置逐渐偏离的导航定位数据,当偏离误差无法被组合导航纠正时发生曳引式拉偏干扰。文中给出干扰方法的定义、信号形式、简化形式,通过半实物仿真实验证明其有效性并对其干扰效果进行了分析。
In order to solve the difficult problem of GPS / INS integrated navigation, a traction pull-off interference method for GPS / INS integrated navigation is proposed. The jamming signal is generated by the interference device so that the GPS receiver in the GPS / INS combination outputs navigation positioning data which is deviated from its actual position gradually. When the deviation error can not be corrected by the composite navigation, the pull-pull interference occurs. The definition of interference method, signal form and simplified form are given in this paper. The effectiveness of the method is verified by the semi-physical simulation and the interference effect is analyzed.
