The article analyzes instruments and systems for measuring the muzzle (initial) velocity of artillery and small arms ammunition of different calibers. Local and foreign devices that are mounted on weapons or which are located at a distance are given. Most of the devices considered in this article can work autonomously, which is an advantage when using them at the landfill. An important component of ensuring the defense capability of the State is the high level of Armed Forces of Ukraine equipment with new high-precision weapons and military equipment and the modernization of existing weapons, which involves verification of weapons samples for compliance with the declared characteristics of the manufacturer (supplier). The effectiveness of the tests depends on the accuracy and quality of the instruments(systems) which are used to measure the characteristics of the weapons. The initial speed of the ball (shell, mines, etc.) is one of the main characteristics of the weapon’s combat properties. It is determined experimentally and by additional calculations. The SL-520 series systems are versatile and precise instruments that allow the effective testing of weapons samples at training grounds. The advantages of these systems are: range of possible measurement speeds, high measurement accuracy, the possibility of measuring the muzzle velocity of all types of artillery and small-arms ammunition of different calibers, self-calibration option for the whole life cycle, integrated GPS time synchronization, the possibility of complex application of typical radars and the duration of autonomous operation.

The article offers recommendations for the project of General requirements for the video registration system for determining the movement of weapons and military equipment test facilities. The analysis of scientific and technical literature and other open sources of information allows us to draw the following conclusion that in the developed countries of the world active scientific work is constantly being conducted to find new technologies, methods, methods and means to improve the quality of testing. Many different scientific studies are related to the need for video recording of test processes (high-speed, thermal, and others). Therefore, during the tests, a variety of video equipment is used, which differs in the principle of operation and technical characteristics. In today's conditions, video surveillance is implemented at all stages of testing weapons and military equipment. The capabilities and technical characteristics of existing modern video equipment require careful study. Based on the analysis and study of video recording capabilities, recommendations were developed for the project of General requirements for the video recording system for determining the movement of weapons and military equipment test objects during the testing of weapons and military equipment delivered to the Armed Forces of Ukraine.

To ensure the successful implementation of various combat missions within the national resistance to aggression against the russian federation, along with units and formations of the Armed Forces of Ukraine and the National Guard of Ukraine, the reserves of the State Border Guard Service of Ukraine also take part in defense activities. They operate as part of combat border commandant's offices and border rapid response units, as well as other units that can be conditionally united under a common name – border rapid response units. In order to succeed in these military operations for border rapid response units, a special role, along with the suddenness, intensity and courage of action, is played by the issue of ensuring their survivability by rapidly restoring their weapons and vehicles. The article reveals the essence and content of the proposed method of rapid recovery of weapons and vehicles of border rapid response units on the criterion of ensuring their survivability. The article presents aspects of scientific research that reveal the concept of the criterion and its essence to assess the level of achievement of the goal of autotechnical support of combat operations of border rapid response units. The essence of the proposed method is to use the criterion of ensuring the survivability of border rapid response units through a compromise of their firepower and mobility. The novelty of the proposed method of rapid recovery of automotive equipment and armament of border rapid response units on the criterion of ensuring their survivability is that, unlike existing ones, it takes into account possible risks and options for border emergency response units in conditions of uncertainty. The use of the main provisions of the proposed method will provide practical recommendations for the organization of rapid recovery of automotive equipment and armament of border rapid response units in combat conditions of a special period.

For some time past the careful attention of researches requires the issues of analyzing qualities of test objects and compliance actually received tactical and technical characteristics with specified operational requirements, it is necessary to get the parameters of high-precision trajectory measurements that will enable comparison (deviation) of the real trajectory from the reference trajectory (pattern trajectory); evaluate the operating benefit of the test objects; identify the causes of nonconformities of tactical and technical characteristics to requirements, which can be detected. Today for measuring the trajectory parameters of the test objects using equipment, which operates on different physical principles. It refers also to the electro-optics equipment, in which implemented process of target tracking for the purpose of obtaining on a real time basis initial information, further processing which will allow to calculate highly precise trajectory parameters of test objects.

The article highlights the practicability of developing our own software for processing video information obtained during testing of weapons and military equipment (WME) specimens. To obtain measurement information of processes which are distributed in space and time, namely: motion trajectories, velocity, acceleration of the object, propagation of gun muzzle blast ejection, dynamics of explosion of ammunition of various purposes. The basic operations of video information processing were outlined: 1) perspective correction; 2) compensation (correction) of distortion (optical effect "fish eye”); 3) scale determination of the video material’s frame; 4) conducting of static measurements; 5) position determination of the image object in a sequence of video stream’s frames. A brief overview of major open-access computer libraries (Accord.NET, VXL (Vision-something-Libraries), OpenCV (Open Source Computer Vision Library)) were conducted. To demonstrate how the above operations were performed by the OpenCV library, examples of the results of using it in Kinovea program were presented. An analysis of the popularity of computer vision libraries was conducted, which made it possible to assess the prospects for their further development and information support. The rationale for using OpenCV in software was fulfilled, that can be developed to process the video information obtained during testing of weapons and military equipment specimens.
