The invention provides a space-time polarization anti-interference method based on an alternate polarization sensitive array, and the method employs the alternate polarization sensitive array as a receiving model, and the array reduces the calculation burden and mutual coupling effect of the method. On the basis of a multilinear constraint criterion and space-time adaptive processing, polarizationinformation of signals is added according to polarization characteristics of satellite signals and interference signals. Compared with the traditional method, the method has the advantages that the influence of the cross-coupling effect of the polarization sensitive array with the orthogonal double dipoles is effectively reduced, and the anti-interference performance is not influenced; the problem that satellite communication and positioning are affected due to the fact that satellite signals are attenuated when expected satellite signals and interference signals are close in incoming wave direction or small in interval is effectively solved. The problem that the anti-interference capability fails when the two-dimensional domain information is similar is effectively solved; two-dimensional domain information is expanded to three-dimensional domain information, joint anti-interference of a space-time polarization three-dimensional domain is achieved, and a theoretical basis is providedfor anti-interference of a satellite receiver.
