中文摘要 | 本文針對微小化主動式電子掃瞄系統前瞻關鍵模組進行開發研究,文中陳述了設計、封裝、組裝、測試ㄧ中心運作頻率為Ka波段之8x8二維相位陣列天線及晶片組模組系統。內容涵蓋設計一CMOS四通道可延展相位陣列系統晶片及測試完成品16顆已封裝並組裝於系統之晶片、八片已安裝之1x8可延展相位陣列天線模組板成品含晶片組、八片已安裝DC穩壓板成品、八片已安裝AD/DA板成品、一片已安裝之晶體震盪板及足夠數目之FPGA控制板與相位陣列校正及數位雷達陣列收發機控制軟體。為求得高雷達效能,精密相位陣列單元之相位校正與控制為關鍵技術。在本文章內採用直接耦合(Direct-Coupled)駐波IQ震盪器,維持本地震盪訊號輸出的振幅固定,因此射頻到中/基頻的增益可以保持不變,大幅增加雷達系統運作時之穩固性。為求易維護性,本文章採用的主體將會是1x8的線性可延展相位陣列模組。系統晶片採用CMOS系統晶片與GaAs前端模組,降低建造成本。透過SiP覆晶方式降低總系統尺寸。FPGA模組相位校正與控制強化雷達系統與電子作戰中自動化與使用便利性。 |
英文摘要 | This work proposed "a prospective critical module for miniaturized active electric scanning system". The Plan is to design, package, assemble, test and deliver a Ka Band 8x8 two-dimensional phased array system. These include, one CMOS four-channel phased array transceiver system IC design with 16 working and assembled dies, eight pieces of 1x8 phased array module boards including mentioned chipsets and antenna-on-board, eight pieces of DC supply module boards, eight pieces of AD/DA module boards, one LO distribution module board, and enough number of FPGA for automatic calibrating and controlling the whole system. Precision phase controls and calibrations are the keys to achieve high RADAR performance. A directed-coupled standing wave I/Q oscillator is chosen to stabilize phase-toamplitude modulation appeared in typical phased array systems. These technologies greatly improve the robustness of RADAR system during operations. To achieve ease-of-maintenance, the systems will be based on a 1x8 linear scalable phased-array module board. CMOS system IC reduces the overall manufacturing cost. SiP packaging technologies reduce overall system physical dimensions. FPGA firmware and hardware calibrate and control the RADAR to automate system operations on battlefields. |
