Study of Parameters Influencing the Accuracy of the SDF Method Localization

Modern military operations increasingly use unmanned aerial vehicles (UAVs) not only for observation and reconnaissance, but also for active localization of radio emission sources. One of the methods used for this purpose is the signal Doppler frequency method (SDF), based on the analysis of the frequency of the signal received by the moving sensor. The paper presents a theoretical analysis and simulation studies aimed at determining the effect of selected parameters on the accuracy of emitter localization using the SDF method. In particular, the factors such as data acquisition time, accuracy of Doppler frequency estimation, carrier frequency and the velocity of the moving sensor were considered. The aim of the work is to indicate which of these parameters are crucial for the quality of localization. We formulate conclusions that can support the development of the resistant to interference and more precise localization systems based on the SDF method. The presented approach can be used both in real armed conflicts and in work on autonomous electronic reconnaissance systems.
