Friend-or-Foe Recognition Algorithm Development for the Corresponding Software Building

M.I. Ogurtsov

Abstract


The year 2022 showed an urgent need to improve the existing systems for recognizing objects in the aerial space, which is caused by the significant increase in the number of technical means (especially unmanned aerial vehicles) on the battlefield. Such a sharp increase in the number of objects that simultaneously take part in combat operations in the air requires the improvement of military object recognition systems, both qualitatively and quantitatively. This requires the development of appropriate new generation Friend-or-Foe algorithms for the objects’ recognition.

The main requirements for recognition systems of aerial objects of civil application were determined. They includes: maximum com- patibility; support for a large number of objects; outdated recognition complexes support; support for alternative ways of recognition; support for alternative data entry methods; determining the coordinates of aerial objects in an emergency situation.

Friend-or-foe recognition systems for military applications are also considered. In contrast to civilian systems, the following basic requirements have been identified for them: 1) Maximum speed of the recognition process. 2) Protection against false positives. 3) Protection against legitimate aerial object imitation. 4) Support for a large number of objects. 5) Protection against cases of loss of a legitimate aerial object. 6) Rotation of the secret part. 7) Protection against false-negative results to prevent friendly fire. 8) Protection against man-in-the-middle attacks. 9) Flexible integration with the NATO block recognition system. 10) Availability of opportunities for purely domestic production and support of the object recognition system. 11) Protection against electronic warfare means. 12) Support for several recognition modes. 13) Automatic blocking of the launch of ground-to-air and air-to-air weapons against objects that confirm their legitimacy by a correct response to a request. 14) Determining the coordinates of aerial objects in an emergency.

Based on the formulated requirements, a new friend-or-foe algorithm for the state identification system for military use is proposed, built based on the state standards, and taking into account the features of its software implementation in order to increase speed. Its implementation will ensure sufficient scalability, stability, reliability, and multi-level recognition.
