本論文發表一個適用於車輛應用的雷達之設計與量測。雷達高度整合了射頻模組、天線以及數位電路。雷達所使用的天線架構為一個透鏡天線以及一個微帶天線餽入的號角天線。天線設計使雷達具有遠距離高方位角辨識能力。天線增益為28.5dBi ，半功率主波束寬度低於3度，雷達系統偵測能力高於100公尺。

The design and measured results of the developed radar sensor for automotive applications are presented in this thesis. The radar is highly integrated with the transceiver module, antenna and base-band circuits. The proposed antenna is composed of a novel microstrip-line-fed horn antenna and a quasi-optic lens antenna. The completed radar sensor with high resolution in azimuth and long detection range capability is demonstrated by practical road tests. The antenna gain is 28.5dBi. And the half-power beam width (HPBW) is narrow than 3 degrees. The maximum detection range is more than 100m.
