The article analyzes the report documentation of the tests in which the Doppler radar trajectory measurement system MFTR–2100/40 and the muzzle velocity measurement system SL-520PE were used to determine the trajectory parameters of artillery armament. The purpose of the article is to provide proposals for standard methods of using Doppler radar systems of trajectory measurements when testing artillery armament and its ammunition. The proposals for these standard methods are based on the experience of using the MFTR–2100/40 radar system and the SL–520PE muzzle velocity measurement system during the tests of the latest specimens of artillery and ammunition and relate to typical Doppler radar systems. When choosing the position and mode of operation of such Doppler radar trajectory measurement systems, it is always necessary to take into account safety measures, instructions for their operation, technical features (capabilities) of radar systems specified in this article, considering the interference environment during firing (shot) of artillery armament and experiment (test) conditions. Placing typical Doppler radar systems when taking measurements in unplanned places is dangerous for the crew and measuring instruments and leads to partial or complete loss of measuring trajectory information and reduced measurement accuracy. Abovementioned proposals are offered to be taken into account when developing methods of trajectory measurements using typical Doppler radar systems during testing artillery armament and its ammunition. Methods of measurements using standard Doppler radar systems of trajectory measurements should be developed in accordance with current standards (GOST 8.010-99, GOST V 15.211-78 and others) for a particular test, taking into account the results of analysis of the characteristics of samples to be evaluated, measuring instruments used, conditions and locations of measurements.
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.
Testing ground measuring and computing complex (TGMCC) is a set of interconnected hardware and software designed to perform measurements and processing of measuring information to determine the tactical and technical characteristics of objects in different conditions of their application, objective evaluation of test results of armament and military equipment (AME). For radar measurements of trajectory parameters of moving objects, mobile and stationary radar stations of trajectory measurements are used, including Doppler radar systems of external trajectory measurements. Such radar stations of trajectory measurements are one of the components of TGMCC. They are designed to measure, process and record the parameters of the trajectories of moving objects in a given spatial volume with a given accuracy and reliability during testing of a wide range of new and upgraded samples of AME, as well as perform measurements along with optoelectronic stations of trajectory measurements, or they could be used separately from them. Therefore, currently there is a problem of creation of mobile testing ground measuring and computing complex which consists in its equipping by modern means of external trajectory measurements, both domestic and foreign. Thus, the proposed recommendations for the integrated application of Doppler radar systems of external trajectory measurements as a part of a mobile testing ground measuring and computing complex will allow to conduct testing and certification of armament and military equipment offered for supply to the Armed Forces of Ukraine more efficiently and with increased quality.
