摘要：
Digital terrestrial multimedia broadcasting (DTMB) passive radar obtains target information by eliminating correlation between reference signal and target echo signal. In order to reduce the computation of multipath clutter cancellation quickly, the PN sequence in digital ground broadcast signal is used to eliminate the multipath clutter in this paper. Compared with the traditional clutter cancellation algorithm, this method has less computation cost and can accurately detect the target signal. Finally, the simulation experiments demonstrate the effectiveness of the algorithm in this paper.
