 Mathematical Model and Algorithm for the Identification Task of Radio- Emitting Objects of Tactical Situation on Data From Ships of Task Force The article presents a mathematical model and algorithm for tasks of radio-emitting objects identification. The identification task partition into component parts is carried out. New approaches to the calculation of the radio-emitting object identification level from geometric and signal features will be found in the article. Authors propose a priority sequence of tasks to be solved based on practice of working with special information. A new mathematical model for constructing the identification evaluation function from signal features is developed. This model is not restricted to the assumption of thelinearity of this function. Algorithms for calculating the threshold values of object identification are presented. An algorithm for the radio object identification is developed under conditions of the computing experiment performed in the MATLAB environment. Following the results of the computing experiment, the algorithm has been defined more exactly, the positive outcomes of using the model have been provided.Passive radio aids, information identification, object identification level, machine learning method.

 The Model for Forming the Flight Profile of an Aircraft Using Dynamic Programming Tools The article deals with the process of forming the flight profile of an aircraft. Calculation and selection of the optimal flight profile of aircraft are some of the most common issues in the tasks related to the planning of aviation operations. The flight profile in the coordinates ‘range-altitude’ is a sequence of areas each of which corresponds to a specific program for changing altitude and speed. The construction of the flight trajectory of an aircraft is characterized by the work with a large number of nonlinearly varying dependent parameters and taking into account the restrictions imposed on flights: the permitted echelons of aviation flight altitudes, forbidden zones with unacceptable meteorological conditions, forbidden zones of action of enemy air defenses. These factors make it very difficult to model the specified process. The application of the mathematical apparatus of dynamic programming in solving this problem can allow the most efficient choice of flight modes of aircraft and optimize the process of forming the flight profile as a whole.Fighter aircrafts, flight profile, optimization algorithm, dynamic programming.

 The Model of the Airborne Alert Charting With the Refueling Opportunity The article deals with aircraft control automation during the airborne alert. The task of airborne alert is a part of the task for fighters to provide the air cover of naval force. A modern approach to solving task in aircraft patrol zonation with air-to-air refueling opportunity is used when examining the automation problems. The approach consists in automation of airborne alert charting with the use of optimal mathematical models of alert aircrafts and air- refueling tankers zonation according to the chosen criterion. The dependence of the chosen criterion upon the quality performance of the ship air defense system is demonstrated in the section on problem definition. The approach allows to combine the mathematical models of alert aircrafts and air refueling tankers zonation tasks into the single algorithm. The models use the methods of linear programming mathematical tools. Also the approach allows to improve the automation level of the process providing naval force air defense concerning fighter aviation.Standing patrol, fighter aviation, distribution, optimization algorithm, refueling.
