The Traffic-Flow Detection Based on Pseudo-Random Coded Radar
A new traffic flow detection system based on pseudo-random coded (PRC) cw radar is studied and developed in this paper. The proposed system can measure the speed of vehicles at a high resolution. The speed can be measured by the Doppler principle, and in the system the good correlation performance of PRC is used to get a high resolution of range and eliminate the interference from nearby lane vehicles. The digital signal processor transforms and processes the signal in time-frequency domain, and gains the vehicle velocity and flow rate rapidly and accurately.
