VHDL Performance Analysis of Correlation Radar with Distance, Speed and Angle Measurement for Automotive Application

Abstract

Radars are general devices for defense, survey & vehicle guidance systems. However the sophisticated design & requirements of costly devices, makes it out of reach to the daily applications. Correlation radars are used as anti – collision system for auto – motive applications. Objective of this system is to design simple, cost effective architecture of the correlation radar. As a consequence, this system will reduce accidents and enhance road safety. This paper proposed an approach to make the device simple, cheap & much compatible for the automobiles. As a result, it can be used for automated vehicle derive system as well as collision avoidance system. 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 will guide about direction of obstacle and also increases the application area of this correlation radar. Principle of this system is to avoid collision between the equipped vehicle and the one in front, or other kind of obstacles (pedestrians, animals, etc). As a result this radar can replace the existing previous version of radar and improve the road safety.
