In this paper, the application of an LMS adaptive filter in one notch polarization adaptive antijamming receiving system is studied. An improved LMS adaptive filter which can be well used in the system is introduced and a new method to get the control parameters of polarization filter is given. Finally, a computer simulation is carried out to analyze the antijamming perfoimance of the system. The result shows that the mentioned polarization adaptive anti jamming receiving technique is effective.\;
