Description: Nowadays, fighter jet is one of the most frequently used types of armament for country border defence. The essential pur-pose of using fighters is air target hitting. It requires most accurate target distance value existing for effective situation control during air battle conducting. Among the main tasks of fighter armament control system are: seeking, detecting, locking the target on and parameters calculating for further using by airborne weapons. To ensure the fulfillment of these tasks, the airborne air-craft on-board equipment includes systems and complexes, on the basis of which the task of providing the airborne weapons with the purpose information is solved. The article deals with the actual question of determining the distance to the target in case of failure of the laser rangefinder of the MiG-29 fighter. The analysis of the functioning of the existing equipment for measuring the range is carried out, the main problem deficiencies are formed. To eliminate the shortcomings of this equipment, our direction provides the methodology development of determining the distance to a visually visible air target based on the relative position of the target and the aircraft. A method of measuring the distance to the target in case of failure of the laser rangefinder using the existing equipment and parameters that are determined by these systems is being developed. The main way to navigate is the informational vertical complex and the IK-VK-80-6 course, a certain value of the roll, pitch and course, and storage of absolute linear speed in three axes. This technology is less effective unlike using laser rangefinder. The reason is error accumulation of parameters that are being measured by used equipment. Though, the developed technology provides target distance measuring enough because of frequent laser rangefinder failures. The relevance of the subject matter is primarily related to the peculiarities of the execution of tasks by a fighter pilot in the conditions of the Operation of the joint forces in the East of Ukraine. On the basis of mathematical calculations, the analysis and comparison of the developed methods is carried out. The relevance of the combined method is determined.
Keywords: laser range finder, target range, quantum optical location station.
