Airborne RF Emitter Localization via Phase Difference Rate of Change

In this research, an RF transmitter localization algorithm using the phase difference rate of change method, which is expected to be applicable in electronic support systems on airborne platforms, is introduced. Traditionally, in RF transmitter localization, the intersection of lines of bearing (LOB) obtained from angle of arrival information taken from different measurement points is used. This method, known as triangulation, relies on LOB having different angles and takes a long time. This situation causes constraints in localization systems. However, the method known as phase difference rate of change, which is considered a direct position determination method, allows positioning instantaneously. Within the scope of the study, a model of the method was established, simulated, and used for positioning purposes.
