Passive radar is known to suffer from high clutter. In this paper, a generalized subband cancellation (GSC) algorithm is proposed to achieve robust clutter rejection. Four major factors are taken into account, namely carrier frequency offset, sampling frequency offset, fractional delay, and hardware frequency response. The GSC algorithm utilizes subband signal processing and tailored clutter subspace construction to solve the problems caused by these factors. Quantitative evaluations demonstrate that the GSC algorithm approaches the optimal clutter cancellation performance. Its effectiveness is also validated using field experimental data.
