The key for phased array antennas with good functions is the use of controllable phase shifters . however , phase quantization errors affect the accuracy of phased array antenna beam pointing badly , which is mainly researched here 其中可控?cái)?shù)字移相器的使用,是相控陣天線優(yōu)越性能實(shí)現(xiàn)的關(guān)鍵,但由此引入的相位量化誤差,嚴(yán)重影響了相控陣天線的波束指向精度。
First , based on phased array antenna ' s mono - pulse goniometry and separate coordinate technology about phase control , the antenna beam pointing error formula , caused by phase quantization error , is derived from linear array and circular array to planar array and cylindrical array 首先以單脈沖相控陣天線測(cè)角原理為基本理論出發(fā)點(diǎn),利用相位控制的坐標(biāo)分離技術(shù),基于線陣、圓形陣等簡(jiǎn)單形式的相控陣天線,推導(dǎo)了平面陣、圓柱面陣等相控陣天線由相位量化誤差引起的波束指向誤差公式。
