Abstract
Techniques are provided for mitigating interferometric angle ambiguity. A methodology implementing the techniques according to an embodiment includes measuring a differential phase of a signal received at an interferometer baseline; calculating a Gaussian conditional probability of an angle of arrival of the signal based on the differential phase; calculating an angular position probability of an object in a target reference frame based on the conditional probability; aggregating the angular position probability with previously calculated angular position probabilities (based on previously selected baselines) to generate a current angular position probability; selecting a next baseline and iterating the process to calculate a next angular position probability; and selecting an angular position probability of greatest likelihood, from the current and previously calculated angular position probabilities, based on an amplitude of the Gaussian distributions, such that the selected angular position probability is associated with a disambiguated angular position of the object.
