Description

The invention relates to defense technology, in particular to the field of weapons testing, and can be used in the development and creation of testing tools and evaluating the effectiveness of the operation of systems for protecting objects from destruction by precision weapons (WTO).

The closest in technical essence to the claimed invention is a test bench [see, for example, patent RU 2263869 C1, F41G 3/26, G09B 9/08, publ. November 10, 2005, bull. No. 31], comprising a control unit, a guidance head mounted on a rotary support device, and a target simulator (phono-target environment). The principle of operation of the test bench is that the target simulator simulates various situations, signals in accordance with the given parameters and emits them in the direction of the homing head, which includes real equipment of the onboard control complex. The homing head receives signals from the simulator and tracks them. The control unit for the signals of the homing head controls the movement of the target simulator relative to the homing head. This simulates the guidance of the WTO on the target, that is, changing the viewing angle of the target simulator while reducing the distance between the target simulator and the homing head.

A disadvantage of the well-known stand is the inadequacy of modeling processes for the actual operating conditions of systems for protecting objects from WTO damage and evaluating their effectiveness, due to the use of homing heads of the domestic WTO, the characteristics and parameters of homing circuits of which do not correspond to the characteristics and parameters of the guidance contours of missiles and enemy bombs. The disadvantages also include the need to simulate a phono-target environment (FSO) corresponding to real conditions, characteristics of objects and their protection systems.

The technical result of the invention is the elimination of these disadvantages.

The specified technical result is achieved by the fact that in the mobile complex for testing and evaluating the effectiveness of the systems for protecting objects from WTO damage, containing a control unit, a rotary support device and a simulator of a phono-target environment, according to the invention, the rotary support device is equipped with a lifting platform and it has a range measuring unit, a receiver of the global navigation satellite system (GNSS) equipment, and N - a channel measuring and recording unit, each the first channel of which contains a signal receiver and an analog-to-digital converter (ADC) connected in series, as well as an information storage device having N + 3 inputs, a data input unit, a series-connected block for modeling the guidance loop of the WTO and a block for evaluating the effectiveness of protecting the object from damage to the WTO , while the output of each n-th channel of the measuring and recording unit, where n = 1 ... N, is connected to the corresponding input of the information storage device, the output of which is connected to the input of the phono-target environment simulator, the output is the range measurements and the receiver output of the equipment of the global navigation satellite system are connected, respectively, with N + 1 and N + 2 inputs of the information storage device; the first, second and third outputs of the control unit are connected, respectively, with the N + 3rd input of the information storage device, the first input of the slewing ring device and the second input of the WTO guidance loop modeling unit, and the first, second and third outputs of the data input unit are connected, respectively , with the second input of the rotary support device, the third input of the WTO guidance loop modeling unit and the second input, the unit for evaluating the effectiveness of object protection against WTO damage, the output of the phono-target environment simulator is connected to the first input eye modeling WTO guidance loop.

The essence of the invention lies in the fact that the slewing ring is equipped with a lifting platform and a distance measuring unit is installed on it, a receiver of the global navigation satellite system equipment and N is a channel measuring and recording unit, each of whose channels contains a signal receiver and an ADC connected in series, as well as an information storage device having N + 3 inputs, a data input unit, series-connected WTO guidance loop modeling unit and efficiency assessment unit protection of the object from damage to the WTO, while the output of each n-th channel of the measuring and recording unit, where n = 1 ... N, is connected to the corresponding input of the information storage device, the output of which is connected to the input of the simulator of the phono-target situation, the output of the range measuring unit and the output the receiver of the equipment of the global navigation satellite system is connected, respectively, with N + 1 and N + 2 inputs of the information storage device; the first, second and third outputs of the control unit are connected, respectively, with the N + 3rd input of the information storage device, the first input of the slewing ring device and the second input of the WTO guidance loop modeling unit, and the first, second and third outputs of the data input unit are connected, respectively , with the second input of the rotary support device, the third input of the WTO guidance loop modeling block and the second input of the unit for assessing the effectiveness of object protection against WTO damage, the output of the phono-target environment simulator is connected to the first input Lok simulation WTO guidance loop.

In the course of testing the systems for protecting objects from WTO damage by the mobile test support complex, two main tasks are solved:

receiving and accumulating information about the object’s radiation and signal reflections from it, including under the conditions of application of protection systems and the presence of interfering radiation by taking measurements and (or) fixing the characteristics of the central federal district in the dynamics of its development (preparatory work);

assessment of the effectiveness of the functioning of systems for protecting objects from WTO damage.

The preparatory work is carried out on the ground in the area of the location of the object to be protected from the defeat of the WTO (object of protection). At the same time, elements of the protection system are located in the area of the protection object in accordance with operational requirements and operate normally. For measurements, the mobile test support complex is placed at a predetermined distance from the object of protection, and the measuring and recording unit is raised to a predetermined height. The distance and height are set in accordance with the test conditions, which are determined, for example, by the type of WTO and its tactical and technical characteristics, range of application, the angles of approach of the ammunition to the target and other features of the application, as well as the terrain and meteorological conditions. The measurement results are stored in an information storage device.

Due to the fact that the measurements are carried out in real conditions, the information received on the object (both during the operation of the protection systems and without them) will coincide with the information at the input of the enemy’s homing head if it were at the point of measurement. If necessary, measurements are carried out repeatedly for various viewing angles and directions of possible attacks on the object.

Subsequently, according to the information obtained during the preparatory work, in the simulator of the phono-target situation, the values of the experimentally obtained signal parameters are extended at the measurement points to simulate the operation of the WTO guidance loop in the required range of conditions for its application. Recalculation is carried out taking into account the influence of signal propagation conditions, the range of possible environmental parameters (humidity, temperature, illumination, transparency of the atmosphere) and other factors. The guidance path of the WTO is modeled with parameters corresponding to the parameters of the guidance loop of a specific type of enemy’s WTO. Based on the simulation results, the WTO miss and the effectiveness of protecting the object from damage are estimated.

Thus, it is ensured that the processes of modeling and evaluating the effectiveness of the real conditions for the functioning of the systems for protecting objects from the damage to the WTO are achieved and, accordingly, the technical result indicated in the invention is achieved.

The structural diagram of a mobile complex for testing and evaluating the effectiveness of the systems for protecting objects from damage by precision weapons is shown in figure 1, where it is indicated:

1 - slewing ring; 2 - N-channel measuring and recording unit; 3.1, ... 3.N - signal receivers; 4.1, ... 4.N - analog-to-digital converters; 5 - receiving device GNSS equipment; 6 - block measuring range; 7 - information storage device; 8 - data input unit, 9 - phono-target environment simulator, 10 - control unit, 11 - WTO guidance loop modeling block; 12 is a unit for assessing the effectiveness of protecting the object from the defeat of the WTO.

Measuring and recording unit 2 is designed to obtain information about the radiation of the object to be protected from the defeat of the WTO, in the application of systems and means of protection, as well as the conversion of measurement results into a digital code. The radiation of the object and the reflection of signals from it are recorded in the dynamics of the protection systems in the ranges of the homing heads of the WTO.

The receivers of signals 3.1, ... 3.N of the measuring and recording unit 2 in the radio range can be performed, for example, according to typical schemes for constructing receiving and analyzing equipment [see, for example, Dudnik PI, Ilchuk AR, Tatarsky B. G. Multifunctional radar systems. - M.: “Bustard”, 2007, p. 41-55]. In the infrared and visible ranges, well-known algorithms for detecting and tracking objects are applicable [see, for example, Alpatov B.A., Babayan P.V., Balashov O.E., Stepashkin A.I. Methods for automatic detection and tracking of objects. Image processing and management. - M.: "Radio Engineering", 2008, p. 73-135]. The signal receivers can be made for different frequency subbands. The received information is converted to digital form using typical ADCs.

The information storage device 7 is designed to store information received by the N-channel measuring and recording unit 2. For its implementation, for example, digital signal recording and reproducing devices can be used [see, for example, Dobykin V.D., Kupriyanov A.I. , Ponomarev V.G., Shustov L.N. Electronic warfare. Digital storing and reproduction of radio signals and electromagnetic waves. - M.: “University Book”, 2009, p. 221-263].

The phono-target environment simulator 9 is designed to recalculate data from the information storage device 7 obtained at the measurement points to other distances of the WTO trajectory to simulate the operation of the guidance loop. Calculations in the radio range can be performed, for example, using known methods for calculating the propagation of radio waves [see, for example, Dolukhanov MP Propagation of radio waves. Textbook for high schools.- M .: "Communication", 1972, p. 19-24]. Recalculation to other observation conditions in the infrared and visible ranges can be performed, for example, according to the methods described in [Alpatov B.A., Babayan P.V., Balashov O.E., Stepashkin A.I. Methods for automatic detection and tracking of objects. Image processing and management. - M.: "Radio Engineering", 2008, p. 66-73, 75-76, 95-101].

The WTO 11 guidance loop modeling block can be performed according to standard guidance loop modeling schemes containing a homing head model, command shaper, stabilization loop and kinematic link similar to those described in the well-known literature [see, for example, Karpukhin V.I., Kozlov S. V., Lazarenkov S.M. Conflict models of aircraft systems of electronic warfare and air defense / Monograph. - Voronezh: VSC VVA VVA, 2013, p. 221-358]. Parameters for modeling the functioning of a specific type of WTO come from the data input unit 8, into which they are entered on the basis of the enemy’s WTO models. The output parameters of block 11 are the misses of the WTO.

In the unit for assessing the effectiveness of protecting an object from damage to the WTO 12, typical calculations of the values of the probability of damage to the object are carried out according to the initial data on the characteristics of the WTO, the parameters of the vulnerability of the object obtained from the input data input unit 8, and the values of the WTO misses. Such calculations can be performed by standard methods [see, for example, Karpukhin V.I., Kozlov S.V., Lazarenkov S.M. Conflict models of aircraft systems of electronic warfare and air defense / Monograph. - Voronezh: VSC VVA VVA, 2013, p. 295-299].

The control unit 10 may be implemented on a computer basis. Using the rotary support device 1, it sets the spatial orientation of the N-channel measuring and recording unit 2 and ensures the operation of the entire mobile complex for testing and evaluating the effectiveness of the functioning of systems for protecting objects from WTO damage.

Mobile test support complex operates as follows. At the preparatory stage, the complex is located in the area where the object of protection is located at a distance, within the length of the final WTO guidance site (tens - hundreds of meters, units of kilometers). According to the data of block 8, with respect to the characteristics of a specific type of WTO, the N-channel measuring and recording unit 2 is lifted and oriented in space. Using the range measuring unit 6 and the receiver of GNSS equipment 5, spatial characteristics of the relative position of the measuring registering unit 2 and the object of protection. Measurements and (or) fixation on the digital media of the emitting and reflecting parameters of the object in the dynamics of the protection system in real conditions of the central federal district. Measurements can be taken at several points on the final section of the WTO guidance path. The results are stored in the information storage device 7.

At the second stage, on the basis of the results of field tests containing information on the parameters of the FCO, in block 11, the modeling of the guidance loop of the WTO is carried out. At the same time, the dynamics of the functioning of the WTO guidance loop is reproduced based on the application of the methods of "statistical equivalents" and discrete approximation of the transfer functions of the dynamic links of the circuit, which allow the use of recursive difference algorithms to calculate the missile error of the WTO, the description of which is given in [Karpukhin V.I., Kozlov S .V., Lazarenkov S.M. Conflict models of aircraft systems of electronic warfare and air defense / Monograph. - Voronezh: VSC VVA VVA, 2013, p. 221-358]. The WTO miss value obtained from the simulation results, taking into account the initial data on the characteristics of its warhead and parameters characterizing the vulnerability of the protection object coming from block 8, is used in block 12 to calculate the values of the probability of damage to the object, the analysis of which allows us to conclude the degree of its protection from WTO

The proposed construction of the complex allows us to adequately assess the effectiveness of the protection of objects, since tests are carried out in real conditions of the central federal district and the functioning of defense systems of objects, and modeling is carried out in relation to the enemy’s WTO parameters. At the same time, the complex allows assessments for different types of ammunition with different homing heads, including combined and integrated types.
