摘要

Global Positioning System (GPS) provides accurate, continuous, world-wide, three-dimensional position and velocity information to users with the appropriate receiving equipment. However, because GPS receiver relies on external radio frequency (RF) signals, they are vulnerable to unintentional interference or jamming. RF interference can result in degraded navigation accuracy or complete loss of receiver tracking. Thus, common GPS receivers equip with anti-jam algorithm to suppress the interference. In order to improve the anti-jam performance, it is meaningful and significant for us study how interference signal affects GPS receivers. In this paper, the interference performance of two single-tone interference against Least Mean Square (LMS) algorithm in GPS receiver will be analyzed. Simulation results show that when there is specific frequency difference and specific angle difference between two single-tone interference under the condition of uniform linear array, the output Jam-to-Noise ratio (JNR) is bigger and single-tone interference have good interference performance against LMS algorithm in GPS receivers.
