合成孔徑雷達

Synthetic Aperture Radar (SAR)

合成孔徑雷達衛星星系計畫發展目標為研製0.7米高解析度X頻段SAR衛星。本計畫現階段主要發展酬載雛型體與關鍵技術（包含高增益天線、千瓦級高功率放大器模組／散熱模組／電力控制模組、高頻寬射頻收發機、SAR中央處理與控制單元、高速大容量固態紀錄器等），以及機載SAR儀器研製與飛行取像測試。本年度主要完成機載C頻段SAR研製與飛試規劃；第一枚SAR衛星架構設計；精進版300瓦高功率放大器模組設計／製作及散熱模組研製；輕型展開式天線（2.7米直徑）展示體；以FPGA實現之高速BFPQ雷達回波資料壓縮演算法設計分析；及船隻偵測圖型識別應用軟體模組等。

The goal of the Synthetic Aperture Radar Satellite Constellation Program is to develop a 0.7m high-resolution X-band SAR satellites. At the present stage, the program mainly develops payload elegant bread board and its key technologies including high gain antenna, kilowatt-class RF power amplifier with thermal dissipation and power control modules, high-bandwidth RF transceiver, Central Processing and Control Unit (CPCU), high-speed large-capacity Solid State Recorder (SSR). In addition, the airborne SAR instrument with flight imaging test is also developed. The main accomplishments in this year are the completion of airborne C-band SAR instrument system and its flight test plan, electrical architecture design of the first SAR satellite, improved version of 300W power amplifier and thermal dissipation modules, demonstration model of light-weight and deployable antenna (2.7m diameter), design and analysis of BFPO radar data compression algorithm by FPGA, and software module for ship detection application.
