VHDL Implementation of Correlation Radar For Automotive Applications

Anti-collision radars are used in automobiles applications to prevent accidents of vehicles by detecting obstacles in front of the vehicles. Generally the correlation radars are used for this purpose, which compute the distance and the relative speed between the vehicles, but problem is that the correlation radars are not capable to measure the angle. In this paper, we are presenting a VHDL design for the correlation radar, which is capable to measure distance, relative speed and angle. The proposed radar uses the two receiver concept to measure the angle of the object. The capability to angle measurement also increases the application area of this correlation radar. Because of this facility, this can be used for auto driving system. The simulation results show that it works perfectly and can be used as low cost, single chip solution for automotive radars.
