Abstract
In this study, FMCW radar system was used because it is Frequency Modulated and the signal emitted from the transmitting antenna uses a signal type called Linear Frequency Modulation (LFM) Chirp signal. Linear frequency modulation allows the frequency of the signal to increase or decrease linearly over time. Linear frequency modulation achieve to increase the range resolution, which is the radar's ability to distinguish between targets, and makes it more protected against electronic warfare techniques. Therefore, it is widely used in military applications. As in every radar system, range resolution is an important detail in FMCW radar systems. The modules used in the radar system have an effect on the range resolution separately, as well as the processing of the transmitted and received signals is of great importance. In a FMCW radar system designed within the scope of this study, an environment with more than one target was created to provide the best range resolution, and a modeling and simulation study was carried out to determine the distances, velocities and angular positions of ambiguity multiple targets by processing the transmitted and received signals with CFAR and MUSIC algorithms.
