主动相控阵雷达

有源相控阵雷达(英语:Active Phased Array RadarAPAR radar),是AESA radar即有源电子扫描阵列雷达的一种。英文Active翻译为“主动”或“有源”,意思是指天线表面的每一个阵列单元都完整地包含讯号产生、发射与接收的能力,也就是将讯号产生器、放大器等等全部缩小放在每一个阵列单元以内,天线不需要依靠讯号产生器以及波导管馈送讯号。由于每个阵列单元都可以单独作为讯号源主动发射电磁波,所以被称作主动相控阵有源相控阵。这是目前相控阵天线发展的主流趋势。

有源相控阵的的每个单元只扫描一小块固定区域。各个模组的讯号的相对相位经过适当调整,最后会强化讯号在指定方向的强度,并且压抑其他方向的强度。 在同样的涵盖范围以内,不需要移动雷达天线也可以满足扫描的需求。此雷达的电子零件需要“快速移相器”,而控制相控阵也需要极高的计算能力。此雷达理论在二次大战时提出,最早使用是用于地面的大型弹道导弹预警雷达上面。空用系统最早是出现在美国空军一架RC-135 Rivet Amber飞机上面进行试验,这架飞机稍后发生意外坠毁。能够使用在船舰上或者是军用飞机上的小型化有源阵列技术要到1980年代才逐渐成熟,成本降低到可以接受的程度。

有源相控阵的好处除了与无源相控阵类似之外,由于取消波导管的配置,电磁波能量在传送过程中的散失得以降低,能量输出得以集中在波束上。此外,波束 讯号的产生是在阵列单元上面,免除传送的线路也就降低噪讯的影响。有源阵列天线在频率的变换与多模式的同时运作方面比无源阵列更有效,当天线表面的阵列有 部分受损或者是故障的情况下,雷达的性能会稍微降低,但是不会无法工作。有源阵列的天线在执行多工模式时,可以将雷达分为几个区块,各自发出波束同时执行 不同的任务。而无源阵列则是以快速波束跳跃的方式在近乎同时的情形下执行多工扫描。由于有源阵列相比于无源阵列省略波导管造成的能量耗损,因此探测距离得 以大幅延长,而无源相控阵雷达的探测距离却由于耗损而稍逊于同功率的传统机械雷达。(Quelle:Wikipedia)
