Statement of the problem. Bearing identification is one of the primary tasks for aviation systems of angle measurement for radio sources (RS) monitoring. Identification process includes finding correct decision of bearing belonging to a certain types of RS and minimization of incorrect decisions. Bearing identification problem is especially difficult in case of several RS located in common plane with bearing finder. Most methods use confidence region with circular shape. However, it can be shown that the correct shape of confidence region (CR) is ellipse with circle being only a special case. Thus, it is very important to find an identification method to work with ellipsoidal CR. Besides not only RS bearing can be used as a source of coordinate information, but other measured parameters such as RS Cartesian coordinates obtained from triangulation.

Goal. To explain an idea of modified adaptive method of bearing identification for ground based RS and to propose identification algorithms based on ellipsoidal CR.

Results. Information required for choosing of size and orientation of the error ellipse is presented which defines CR boundary with center in estimated position of RS. Modified adaptive method of bearing identification for ground based RS is proposed. It is intended for single position aerial monitoring systems and uses angular identification with circular CR and correction of RS position estimates.

Identification methods of RS position with ellipsoidal CR are developed.

Practical value. Increased probability for correct identification due to using ellipsoidal CR that more accurately describes error distribution for RS position estimate.
