为了干扰敌方GPS卫星导航设备,使其无法提供正常的导航信息,文中提出了一种根据探测到的飞行器轨迹,通过在每颗卫星上施加不同的传播时延和多普勒控制量来实现位置和速度同时欺骗的方法,并给出欺骗控制量的计算算法。该干扰技术适用于GPS民码和军码方式下的导航欺骗,且不易被检测和抑制;为导航战下的卫星对抗提供了有效的干扰手段。

To achieve the goal of interfering enemy GPS navigation facilities, this article advances a new deceptive jamming approach which could realizing dual deception both on the position and the speed, and provides an algorithm to calculate the deceptive control variables. The major jamming process is detecting the track of the target, calculating control variables of each satellite, and transmitting the deceptive signals. This method is adapted to both GPS CA code and GPS Precise code, what more important is it is much difficult to be detected and restrained, in a word; it provides a new efficient satellite countercheck in the navigation war.
