摘要：

This letter demonstrates the structure of the passive radar using TV signals. Because the TV signal is a kind of pseudoperiodic signal, the matched filtering of color TV signals would yield high sidelobes which cause the range ambiguity. To overcome this problem, the mismatched filter is proposed to suppress the correlation sidelobes of matched filtering of TV signals. By utilizing the iteration process, this method could achieve the required peak sidelobe level. The impacts of the noise and target movement on mismatched filtering are also analysed. Simulation results are included to demonstrate the effectiveness of the proposed technique.
