引言本文叙述独特的一类雷达信号,称作四相编码,它是又一种可以用于脉冲压缩的技术。这种编码信号由J.W.Taylor.Jr.提出用于雷达,并在过去的十年中取得了成功的应用;其工作性能在三个重要领域,即辐射频谱、接收滤波器的失配损失和脉冲压缩用数字硬件来实现时的距离采样损失方面,都胜过采用矩形子脉冲的相位编码。表1给出典型数据。并且,与线性调频相反,匹配接收机输出具有较低的距离旁瓣可满足恒虚警率处理;因此,不必为了利用加权解决旁瓣问题而牺牲灵敏度。 Introduction This article describes a unique class of radar signals, called four-phase encoding, which is another technique that can be used for pulse compression. This encoded signal was proposed by JW Taylor et. Jr. for use in radar and has been used successfully in the past decade; its performance is in three important areas: the radiation spectrum, the mismatch loss of the receive filter, and the impulse Compression using digital hardware to achieve the distance when the sample loss, than the use of rectangular sub-pulse phase encoding. Table 1 gives typical data. And, as opposed to chirp, matching the receiver outputs with lower range sidelobes can satisfy the CFAR processing; therefore, it is not necessary to sacrifice sensitivity for using side-lobe issues with weighting.
