Abstract

Abstract: To eliminate the range sidelobe and improve the multi-target range resolution of passive radar using TVsignals, the mismatched filter is proposed. Based on minimizing the ISL (Integrated Sidelobe Level), the PSL (Peak Sidelobe Level) is approached by the iteration process. Simulation results indicate that not only the range resolution is improved but also the correlation sidelobes are suppressed after mismatched filtration. So the multi-target detectability of passive radar using TV signals is enhanced.

Key words: color TV signal, multi-target, mismatched filtration, sidelobe suppression
