Multiple Vehicle Detection using C-OFDM Based RADAR for Advanced Collision Warning

Abstract

This paper proposes the use of Coded- Orthogonal Frequency Division Multiplexing (C-OFDM) to detect a large number of vehicles on the road. The C-OFDM technique enables a high doppler tolerance over the conventional radar. It is very important to determine the moving vehicle and road-side parked vehicle to take the proper reaction according to the diverse traffic situation. Day-by-day growing vehicular speed and traffic congestion make the task more difficult to detect a large number of surrounding cars on road. More number of the vehicles lined up in a row also makes the situation challenging, as it creates a blind zone in a lane over the road. Various remote sensing systems are being evaluated in the present road traffic scenario. Authors have successfully developed the model to get the desired performance by utilizing the concept of coded-OFDM technology in RADAR signal processing. It also combats the interference while detecting multiple vehicles.
