Beam forming anti-interference method based on vector tracking loop

The invention relates to the field of vector tracking loops of an array antenna and a receiver of a global positioning system, in particular to a beam forming anti-interference method based on a vector tracking loop. The beam forming anti-interference method provides local reference signals for a beam forming device based on an array antenna and ensures normal work of the vector tracking loop. The beam forming anti-interference method includes the steps that the array antenna receives signals; carrier waves in the satellite signals are stripped off; the optimal weight of an array is solved; pseudorange measurement values of all current tracking channels are calculated to obtain the position of a carrier; the vector tracking loop is built. All interferences irrelevant to the satellite signals can be restrained, and the beam forming mode in the method belongs to one of blind beam forming. The vector tracking loop can easily track the satellite signals with the interferences restrained, is not prone to losing lo
