Abstract

In this paper we address the design of a distributed passive radar sensor network system, including the power allocation among sensors, as well as linear signal fusion, considering the channel state information (CSI) estimation error. Analytical solutions are obtained for each case, achieving an optimum performance. In particular, it is assumed that both sensing and communication wireless channels are estimated erroneously, however, with a known error covariance. The performance of the proposed methods is numerically evaluated over different levels of thermal noise and CSI error, where a superior performance is observed compared to the available designs which assume the availability of perfect CSI.
