Abstract

The received signal model of polarization sensitive array is presented under array mutual-coupling condition

then mutual coupling error is decomposed of orthogonal-array-element-factor-error and array-factor-error

which represent signal polarizational information error and spatial information error respectively.Under array mutual-coupling condition

we give the mathematical expressions of some important filtering parameters

such as spatial matching coefficient

polarizational matching coefficient

and the maximum SINR.Then under condition of one interference source

effect of array mutual coupling on filtering performance of polarization sensitive array is analyzed.
