Abstract
Satellite navigation system has been widely used in various fields, because of the signal which is received on the ground is weak and the low ratio of signal to interference, the signal is susceptible to be interfered. The adaptive antenna system using power inversion algorithm with information technology is very suitable for the weak signal and strong interference. The paper presents a detailed analysis on the principle with information technology. By building the hardware circuit in the QuartusII, the self-adapting anti-interference system of power inversion algorithm with information technology which based on Linearly Constraint Minimum Variance (LCMV) criterion can be achieved. The correctness of the theoretical analysis and correctness of the design are verified by experiment, the requirements of satellite navigation receiver on the side of anti-interference has been also proved.
