Özet:

In this thesis, radio direction finding (DF) systems are examined, implementation and measurements for GSM mobile phones are done by using 6-element uniform circular Vivaldi antenna array and uniform circular monopole antenna array which is used asWatsonWatt antenna. Although degrading in performance of DF is expected, only one receiver unit is used in angle-of-arrival (AOA) to measure received signal strength (RSS) from each antenna elements to obtain low cost and small sized set-up. Moreover three di erent algorithms are implemented with the DF arrays Least Square (MLS), Maximum Likelihood (ML) and Multiple Signal Characterization(MUSIC). Finally experimental performance evaluation of amplitude comparison DF set-ups with single receiver will be given in this study.
