The Information Eztraction Algorithm for a Traffic Detection Radar Using ISAR Principle

摘要：

As a wireless sensor,the traffic detection radar (TDR) is recently a new application at civilian areas. The system can provide various types of realtime information about the moving entities day-andnight in all weather conditions.However,the price to realize the accurate information extraction from the echo signals is an efficient mathematic algorithm.In this paper,the date acquisition model of the TDR based on ISAR principle is firstly established. Then,the velocity measurement and length estimation algorithm using the minimum entropy criterion is presented. The experimental results of a prototype radar system are given to demonstrate the validity of the proposed methodology.
