Polarimetric Detection Scheme for Passive Radar based on a 2D Auto-Regressive Disturbance Model

Suitable strategies to exploit polarimetric diversity have been proved to be able to enhance the target detection capability of passive radar (or passive coherent location - PCL) systems. In this work, the authors describe a novel polarimetric adaptive detection scheme, based on a two-dimensional autoregressive model for the disturbance. The effectiveness of the proposed strategy is shown against experimental data collected by means of a FM radio based multi-channel PCL prototype. The obtained results are also compared with alternative polarimetric detection schemes in order to provide a first insight into the benefits of the newly proposed solution.
