Milimeterwave FMCW radar design

İçöz, Dilşad
In traffic radar system, Frequency Modulated Continuous Wave (FMCW) will be used since these radars are preferred in short distance and high range resolution systems. The system to be constructed is not only a system operating with Doppler principle and detection of speed; on the contrary a functional radar is planned to be produced. In various traffic radars in use, Doppler shift constituted by the targets causing high reflection within detection field is measured and the measured speed corresponding to this shift is seen to exceed the limits. In case of cars more than one, their speeds cannot be measured separately. In this FMCW Radar system, it is possible to identify the targets’ distance and speed. The speed information of the target will be specified by Doppler frequency and also as a result of position monitoring, the speed will be determined out of the position change occurring in the unit time. These features, in multi lane road, will be used both for different lanes and also for the cars moving at the same lane but in different ranges. The radar system designed in this study is an easy to use, low power consuming device which can be mounted into the car. Only the active part of the system is off the shelf products and the other RF cards are designed and produced. As a result, a low cost traffic radar will be produced
