| dc.description.abstract | 合成孔徑雷達（SAR）提供了全天候的廣泛應用以及高分辨率成
像能力。隨著技術的發展和地球觀測需求，一般期望建構寬帶取像，分辨率高，以獲得更好的詮釋和目標識別能力、不同方位和角度的多維信息，以及在城市或其他複雜的環境有更好的成像能力。而透過採用MIMO（多重輸入和多重輸出）技術可望達成上述需求。
根據多輸入多輸出（MIMO）雷達的最新進展的啟發，本文基於
MIMO 技術發展合成孔徑雷達成像方法；利用多個發射器和接收天線
單元配置，可以實現高分辨率SAR 圖像。MIMO 的性能經與傳統的
SAR 模擬作相對比較，結果顯示MIMO 技術在相同的系統頻寬下有
高分辨率成像的優越性。

| dc.description.abstract | Synthetic Aperture Radar(SAR) has won widely application and rapid growth in the last 5 decades because of its high resolution imaging capability under all-weather and all-day. With technology evolution and earth observation demands, it is highly expected that the system provide
wide swath imaging with high resolution, better interpretation and target recognition ability, multi-dimensional information of different aspects
and angles, better imaging capabilities of urban and other complex scenarios etc. By employing MIMO (Multiple inputs and multiple outputs) technique, these requirements may be achieved to a certain extent.
Inspired by recent advances in multiple-input multiple-output (MIMO) radar, this thesis develops a method of synthetic aperture radar imaging utilizing MIMO technique by exploring multiple transmitters and receivers antenna elements configuration. The images performance of the proposed method has been compared with conventional SAR through numerical simulation. Result shows the superiority of the MIMO-based SAR in high resolution imaging under the same system bandwidth.
