Rejection of abnormally large direction-finding errors in the process of resolving the measurement ambiguities in phase direction-finders implementing the maximum-likelihood method

Abstract

An algorithm for improvement of the accuracy of small-sized phase direction finders by rejecting abnormally large errors in the process of resolving the measurement ambiguities is proposed. Design relationships that characterize the efficiency of the algorithm are obtained. The theoretical propositions are validated by digital simulation of the operation of a three-base direction finder and by its full-scale test.
