Analysis of passive Direction Finding using combined time and phase methods

This thesis examines the possibility of a combined time-phase Direction Finding (DF) system by modeling a hypothetical aircraft platform with a high Time of Arrival (TOA) accuracy. Algorithmic methods, required hardware tolerances, and potential benefits over conventional linear phased array interferometers are evaluated. This algorithm cannot provide the same bearing accuracy as conventional phase interferometers over common radar frequencies; however it provides tactically useful Direction of Arrival (DOA) information while using less hardware assets than a phase interferometer covering the same spatial region.
