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角原理為基本理論出發點,利用相位控制的坐標分離技術,基於線陣、圓形陣等簡單形式的相控陣天線,推導了平面陣、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。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
其中可控數字移相器的使用,是相控陣天線優越性能實現的關鍵,但由此引入的相位量化誤差,嚴重影響了相控陣天線的波束指向精度。Influence on performance of interference localization using satellite multiple - beam antenna with pointing error
衛星多波束天線指向誤差對干擾源定位性能的影響Besides, it ’ s also very convenient to add many kinds of phase errors required by the phase error compensation and sar image processing research farther. for imaging algorithms, range - doppler algorithm is extended to broadside stripmap airborne bistatic sar successfully
另外,在我們方法的流程中可以方便地加入載機運動參數誤差、天線波束指向誤差及頻率源的穩定性等各種相位誤差,也為今後進一步研究相位誤差補償及圖像處理等技術打下了良好的基礎。分享友人
