TY - RPRT A1 - Jackson, Shane William A1 - Guerin, Daniel R. AB - This paper describes the development of a phase interferometry direction finding system for an airborne platform developed for MIT Lincoln Laboratory. A phase interferometer uses the phase difference to determine the Angle of Arrival (AoA) of a received signal. The team utilized three antennas to resolve phase ambiguities and determined the AoA for received electromagnetic signals in the X band to within 0.1 degrees in simulations including realistic noise models for a 170 degree field of view. A prototype was implemented using an FPGA-based board for data acquisition connected via USB to a PC for analysis, which connected to another PC via a TCP connection for display. The team developed a graphical user interface for the system to display results to a system operator.
