Research on Anti-jamming Technology of Dual-polarized Antenna Array
The complex electromagnetic environment of modern battlefields requires strong robustness of satellite navigation anti-jamming receivers.A polarization-sensitive array uses polarization information to increase the dimension of processing signals and can be applied in navigation to improve the anti-interference performance of the receiver.In this paper,the anti-jamming of the dual-polarization array in a complex electromagnetic environment is studied.The signal model and the dual-polarization array are in-troduced,and the amplitude and phase information obtained by finite element simulation on HFSS are then used to synthesize the steering vector and simulate it in MATLAB to prepare the anti-jamming ability of the ordinary array and the dual-polarization array.The real data is measured in a darkroom to verify the simulation results.The satellite collection positioning test was carried out on the roof to compare the positioning results of the ordinary array and the Dual-polarization array.The simulation and experiment shows that the dual-polarization array can suppress super-degree-of-freedom jamming and has good robustness under low elevation angle jamming.The dual-polarization antenna does not change the antenna size and can maintain the receiver miniaturization while keeping good robustness.
