序列波瓣控制特别适用于方位上作机械扫描和仰角上作频率-相位扫描的雷达。相位扫描的目的是,使波瓣在基本上垂直于机械扫描平面的垂直面内,也就是在仰角平面内移动。频率扫描提供一种微动扫描,并在机械扫描方向上至少提供一种基本的扫描。利用由方位机械扫描的两个微动方位波束位置之间引入的时间延迟来编制频率扫描程序。因此方位测量,也就是对可能包含目标的两个波束之间的测量是在相同的频率上进行的。从而方位测量就与由作为频率函数的雷达目标截面的随机变化而产生的频率闪烁无关。
Sequence lobe control is particularly suitable for azimuth for mechanical scanning and elevation for frequency - phase scanning of the radar. The purpose of phase scanning is to move the lobes in a vertical plane that is substantially perpendicular to the plane of the mechanical scanning, ie, in the elevation plane. Frequency scanning provides a jog scan and provides at least one basic scan in the machine scan direction. The frequency sweep procedure is programmed using the time delay introduced between the two jog azimuth beam positions of the azimuth mechanical sweep. Therefore, azimuth measurements, that is, measurements between two beams that may contain a target, are made on the same frequency. The azimuth measurement is therefore independent of the frequency flicker that results from a random variation of the radar target cross-section as a function of frequency.
