This paper deals with the problem of clutter cancellation in passive bistatic radar (PBR), the cancellation performance of the frequency-domain block least-mean-square (FBLMS) algorithm is limited in presence of the clutter ahead of the reference signal. In order to address it, the discarding point-FBLMS (DP-FBLMS) algorithm is proposed, which discards appropriate points of the reference signal, and...
A new robust adaptive beamforming based on phase extraction is proposed in this paper. The steering vector (SV) is firstly estimated by iterative procedure, and then the angle sector of the desired signal can be determined by using the phase information of the estimated SV. By using the estimated angle sector, the interference-plus-noise covariance matrix can be calculated by Capon spectral integration...
In order to remove desired signal component from the sample covariance matrix, a novel robust adaptive beamformer is proposed based on desired signal covariance matrix estimation. The desired signal direction is first calculated based on the first-order Taylor series approximation, and then the desired signal's steering vector and power are estimated by using iterative robust minimum variance beamforming,...
In this study, the target detection based on single surveillance channel is proposed in passive bistatic radar (PBR) system. The reference signal is recovered from the covariance matrix. The cancellation performance of the recovered reference signal is further investigated, and the reason for the poor cancellation performance is also analyzed. In order to improve the performance, the maximization...
