    Abstract:

    The mutual coupling between the antenna elements based on the Power Inversion(PI) algorithm deteriorates the performance of the space-time adaptive anti-jamming. Common solutions to solve the problem are analyzed and compared. A new method which can be applied to reduce the coupling in the anti-jamming satellite navigation positioning between the antenna elements is proposed. The method reduces the mutual coupling between the antenna elements by loading the electromagnetic resonance absorber in the satellite navigation anti-jamming antenna array. The experimental data show that the method can reduce the mutual coupling between the arrays by 10 dB, and therefore the anti-jamming receiver can suppress the maximum Jamming-to-Signal ratio by 5 dB.
