Auxiliary polarization sensitive array (APSA) and performance analysis

In this paper, an auxiliary polarization sensitive array(APSA) model is proposed, which can reduce the cost of receiving polarization information and further improve the performance of the filter. On the basis of a single polarized linear array, a partial array element is selected to transform into an orthogonal dipole array element, so that the array has the ability to receive polarization information. At the same time a new steering vector and received signal model are constructed. Received signal is filtered based on that, and the filtering capability and performance of the array are analysed in detail. The computer simulation shows that the proposed array model can effectively improve the filtering performance of the traditional array. The simplified structure can effectively reduce the cost of the traditional polarization sensitive array on the premise of guaranteeing the signal to noise ratio of the receiving letter.
