Abstract
The traditional adaptive nulling anti-jamming array antenna does not consider the effect of nulling on the antenna phase center when performing anti-jamming calculations, so that the antenna phase is not constant and causes positioning errors. This article starting with analyzing the anti-jamming of the adaptive nulling antenna array, the influence of the null depth on the phase change is deduced, and a method to control the null depth is proposed to reduce the phase error caused by the array antenna by controlling the null depth. The simulation results verify the rationality and effectiveness of the algorithm, and can be used to improve the positioning accuracy of GNSS receivers using anti-interference array antennas.
