DIRECTION-FINDING AMBIGUITY RESOLUTION IN LONG BASELINE INTERFEROMETERS USING RANDOM FOREST REGRESSION

Abstract: an apparatus includes multiple antennas each configured to receive one or more incoming signals. the apparatus also includes at least one processing device configured to receive antenna measurements associated with the one or more incoming signals, where the antenna measurements include phase measurements associated with the one or more incoming signals. the at least one processing device is also configured to process the antenna measurements using multiple decision trees of a random forest regressor, where the decision trees are configured to generate multiple initial predictions of an angle of arrival associated with the one or more incoming signals. in addition, the at least one processing device is configured to combine the initial predictions in order to generate a final prediction of the angle of arrival associated with the one or more incoming signals.
