Özet:

In this thesis, nine different methods aiming calibration of Phased Array Antenna (PAA) and Multifunctional Radars which employ PAA are presented. Those calibration methods are described, procedures of the methods are explained in detail, and information about constraints and measurement restrictions of those methods is given. As one step further, comprehensive work is focused on Multi-Element Phase Toggling (MEP) method and Rotating Element Vector (REV) method. Results of simulations are shown, theoretical and practical aspects of calibration methods are analytically elaborated. MEP and REV methods are experimentally implemented on a phased array receiver. Results of indoor and outdoor measurements are also presented in the scope of this thesis.
