以相位角資訊設計車輛雷達偵測演算法

Abstract

車輛偵測器為道路交通資料收集系統中之重要一環，設置於道路當地之偵測器，可即時分析出最貼近當地之交通資訊，提供用路人與交通工程師一個可靠性指標，有效降低錯誤決策所產生之風險，以提高用路人之行車品質。此外，所有交通管理策略必頇仰賴正確資料收集系統的資訊，方能有效制定、分析與執行交通管理策略。本研究擬透過相位角資訊，針對調頻連續波雷達回波資訊進行分析，建立一偵測演算法，期能應用於車輛偵測之上。並透過此演算法獲得交通參數，並提供智慧型運輸系統之應用。

Vehicle detector plays an important role in traffic surveillance system. Vehicle detector is installed among roads and provides real-time information nearby. Road users and traffic engineers can make use of the traffic information; and decide the optimal response. This research will design a detection method based on the phase information from frequency modulated continuous wave radar. This study also tries to implement the detection method on vehicle detecting and provide traffic parameters that suitable for intelligent transportation system.
