摘　　要：对彩色电视信号的脉冲压缩进行了研究.利用失配滤波器对电视信号经脉冲压缩后出现的旁瓣进行了抑制.经过失配滤波后,使电视信号脉冲压缩后产生的旁瓣得到了明显的抑制,提高了主旁瓣比,增大了电视信号作为雷达照射源时的不模糊距离.Pulse compression for color television signals is investigated. A mismatch filter is used to suppress the sidelobe resulting from pulse compression of color television signals. By using the mismatch filter, the sidelobes of pulse compression are suppressed and the unambiguity range of radar using color television signals as an illuminator is enlarged.

关 键 词：彩色电视信号 失配滤波 旁瓣抑制
