Özet:

Frequency Diverse Array (FDA) is a recent concept with lots of advantages that are emerged for the radar applications. In order to implement FDA practically, Linear Frequency Modulation (LFM) based FDA is recently offered. A tunable oscillator with delay lines is enough for the implementation. This novel design caught up the gaps of the FDA for a cheap implementation. In order to implement radar, there should be lots of features in the signal processing as well as in the RF front-end. One of the important features of radar is the direction finding (DF). In this thesis, various methods for the implementation of DF for LFM based FDA radar are proposed. In the flow of the thesis, theories behind the FDA and LFM based FDA are reviewed. Two methods for the implementation of the DF for LFM based FDA are suggested and demonstrated with the experiments. Results, possible improvements and future studies are shared with the reader.
