在隐蔽锥扫雷达天线系统(特别是频率捷变雷达的此类天线系统中,和、差信号高频相位差及其大小对雷达跟踪精度和跟踪灵敏度影响很大,本文对此进行一些简要讨论,分析相位差所引起的调制波形畸变,提出一种简单实用的相位调配方法。下面的讨论以机械调制器(旋转耦合环)和四喇叭馈源天线系统为例,其高频和、差信号网络方框图如下:
In concealed cone sweep radar antenna systems (especially such frequency-dependent radar systems), the high-frequency phase difference of the difference signal and its magnitude have a great influence on the radar tracking accuracy and tracking sensitivity. , Analysis of the phase difference caused by the modulation waveform distortion, put forward a simple and practical method of phasing the following discussion to mechanical modulator (rotating coupling ring) and four-horn feed antenna system, for example, the high frequency and, the difference signal Network block diagram is as follows:
