The Firing Tables Compiling of a new type of the very low altitude interception device is studied in this paper. Based on the analysis of drag coefficient identification during the date processing of the Firing Tables experiment, and the theoretical trajectory correction, then according to the defects of the traditional methods for the Compilation of Firing Tables, a new method of determining the correction data is developed which replaces the simple data with the correction function. This method will reduce the error to an obvious degree.

The Impact

The paper attempts to make a model mechanism of a traffic accident involving an unmanned vehicle to solve a number of criminological, criminal-legal and criminalistic problems using the characteristics of the traffic crime mechanism available in theory. Its elements (vehicle, information system and situation) are highlighted, the contents are disclosed, the role of each of them in the etiology of a transport accident is shown. It is noted that the personal factor is not included in the mechanism of a traffic accident; this must be taken into account when criminalizing the corresponding act, which consists not in violating traffic rules, but in low-quality special software. It is stated that in the mechanism of a transport accident, the information system is of fundamental importance, combining the role of both the driver and the information system itself, which is necessary to ensure the safe functioning of a mechanical vehicle. Because of this, it is not necessary to study the reliability of the information system, but the impact of information support on the safety of a highly automated vehicle. Of particular importance is the problem of the so-called uncertainty characterizing the state of the information system. The authors determine the ways of further research of the mechanism under consideration based on the so-called security threat map for the operation of an unmanned vehicle in the context of possibility of interference in their work from the outside (In the software system, by affecting the road infrastructure, etc.).

The purpose of the study was to analyze the influence of the type of the underlying surface forest cover on the level of SNS radio signals reflected from the surface and, accordingly, on the aircraft user equipment efficiency at low-altitude flying. By mathematical simulation, we analyzed the dependences of the signal-to-noise ratio on the elevation angle of navigation spacecraft of the working constellation and the aircraft flight altitude for different types of forest cover. Findings of research show that the rugged barren terrain is characterized by the highest noise level, while the lowest noise level is typical for the thin forest. This can be explained by the fact that most electromagnetic waves penetrate deep into the forest, where they are absorbed due to multiple reflections. Moreover, the thicker the forest cover, the lower the degree of absorption and the higher the noise level.

The paper considers the problem of the synthesis of a low-point model of the relief of the underlying surface. The model can be used to conduct semi-null simulation when the radar is operating in low-altitude flight mode. A method for defining a relief in the form of a piecewise broken approximation is proposed. An algorithm is presented that allows real-time, for a given relief, to calculate for each of the elements of the resolution in range its angular position and angular dimensions. These parameters determine the expectation of the angular noise and the width of their probability density, respectively. The ability to work in real time is provided using a straight line in a spherical coordinate system when defining the relief. The recommendations on the choice of a geometric model from the previously justified family are given. The synthesized models provide a given form of the correlation functions of angular noise and adequately replace reflections from distributed objects. Geometric models can be used as the basis for matrix simulators of reflected electromagnetic waves.

Field Variability

The scientific and technological progress in the agricultural production is based on the application of digital technologies of “smart agriculture” and precision farming, which is its key segment. Precision farming is a global trend of the adaptation of agricultural technologies for crop production to within-field spatial variability of crop formation conditions. It is necessary to quantify the degree of heterogeneity of these conditions and determine the boundaries of their variability in a given agricultural field. Based on the analysis of the available approaches to the within-field variability assessment, the paper substantiates the expediency of searching for new, more precise and inexpensive methods for solving this problem. Due to the large area of Russia, there is no alternative to the technology of remote sensing of the Earth in the information support of precision farming. The proposed new method of within-field heterogeneity detection is based on the use of optical criteria (reflection indexes), characterizing specific and non-specific features of spectral characteristics of crop canopy under the impact of various stress factors. Under controlled conditions, using a special spectrometer, a specific list of reflection indices and a set of quantitative indicators for each criterion was obtained to assess the physiological state of wheat under optimal conditions and nitrogen and water deficiency. The obtained results provide new possibilities for automating the process of interpretation of hyperspectral satellite images in order to identify and reveal the boundaries of the negative effects of stressors that inhibit the growth and development of crops. The relevant algorithmic scheme of the method implementation is considered in the paper.
