摘　　要：欺骗式干扰对全球导航卫星系统(GNSS)构成了严重威胁。目前,大多数定位欺骗源的方法依赖于多个已知位置且时间同步的静止接收机,为此提出了一种新的定位转发式欺骗源方法。该方法只需一个静止接收机,避免了同步时钟和多个接收机间通信的复杂性。同时接收机位置无需预先确定,仅通过观测欺骗信号,利用卫星的位置、速度及多普勒频移量定位欺骗源。本文推导了新算法的定位原理,并通过数值分析和模拟信号仿真验证了该方法的有效性。Spoofer poses a serious threat to Global Navigation Satellite Systems(GNSS).Currently,most methods for locating spoofed sources rely on multiple stationary receivers with known locations and time synchronization,whereas a new method for locating meaconer is proposed,which requires only one stationary receiver and thus avoids the complexities of synchronizing clocks and communicating among multiple receivers.The receiver's position does not need to be pre-determined,and the deceptive source can be located by observing the deceptive signal,using satellite position,velocity,and Doppler shift.This paper derives the positioning principle of the new algorithm and verifies its effectiveness through numerical analysis and simulated signal simulation.
