主脉冲信号 [
zhǔ mài chōng xìn hào]
main bang
- 二相码信号是一类常见的脉冲编码信号,但码较短时,匹配滤波的主副比不高,需要采用旁瓣抑制技术。
For short biphase codes,the main lobe to sidelobe ratio of pulse compression is low,so sidelobe suppression is necessary. - 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.
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.
