Description

The network automated system for transmitting radar information (CASP RLI) is designed to transmit radar information (RLI) from sources to RLI consumers with minimal delays in the transmission and processing of RLIs through the use of high-speed communication lines and network processing algorithms.

The scope and predominant use of the invention are automated radar information transmission systems (ASR RLI) designed to provide RLI of all consumers in the area of responsibility in terms of repelling air attack means, detecting violators of airspace boundaries, aircraft flight modes during combat duty. SASP RLI can be used to build a unified automated system for radar reconnaissance and airspace control.

Known ASR RLI [1, 2], consisting of several sources of radar scattered across the terrain, which include radar stations and complexes (radar and radar), closed to complexes of automation equipment (KSA) of various levels (company, battalion, brigade) .

From the sources, the radar image is transmitted to the command post (CP) of the KSA, from where it is issued to the command post of a higher level (VKP), where it is summarized with information from other sources and subordinate KP of the KSA. After which the information is issued to the radar users. Consumers of radar can be anti-aircraft missile systems and systems of anti-aircraft missile forces (ZRV), fighter aircraft (IA) and radio engineering troops (RTV).

The disadvantage of the TSA radar data is a significant delay (up to several minutes) of radar delivery to consumers [2], which is unacceptable at modern speeds of flying objects, because during the delay, the picture of the air situation changes significantly.

The delay time is caused by the need for multiple processing and re-identification of targets at the KSA at each level, the low speed of the tertiary processing algorithms.

Known global information network (GIS) of the US Department of Defense (MO) [3]. This GIS refers to the strategic level of management. All information from sources is processed in processing centers equipped with supercomputers and located geographically in eighteen points of the globe. The disadvantages of this system are a large number of communication channels and high requirements for the bandwidth of the network providing these channels for the delivery of information from sources to processing centers and back to consumers. This leads to stationary processing centers and, as a consequence, vulnerability. It is likely to assume the distinction of processing centers by areas of responsibility for information processing, which deprives them of interchangeability. At the same time, in the GIS of the United States of America there is no processing of information before it enters the network nodes (local servers).

A known method of network processing of radar data [4], which allows to reduce the time of delivery of radar data to various consumers from various sources, however, its implementation is not given in the patent materials.

The closest analogue (prototype) of the present invention is a radar processing device [5], which provides radar delivery to consumers with a minimum delay. The specified device consists of a number of sources and consumers of radar data connected via a gateway of telecode information (SHTKI) with a network information structure (SIS) in the form of a server, as well as a CP and a computer network (CS) connected to the SIS, and works as follows: information about the air situation through SHTKI it is supplied to the server and after processing on the server it is issued to consumers connected to the device through SHTKI, where the data is converted in accordance with applications received from consumers, without waiting for verification and acceptance of solutions on the CP, while converting the network protocols into a protocol for pairing with the consumer. Information about the current air situation is published on the server for issuing it through the COP to all interested consumers in real time. At the same time, when the device in question is connected to the existing in reality KP KSA, built on a hierarchical basis, it loses its advantages in reducing the processing time and delivery to consumers of radar data, which then enters the system with the previous construction and processing principles.

In addition, this device, connected to the existing control system, cannot implement the principles of situational awareness, the possibility of rapid changes in architecture, survivability, mobility through other KSA.

The main essence of the invention is the connection to each KP of the SAM, IC, RTV device [5] and the connection of these devices using high-speed communication lines with a computer network.

The technical result of the invention is the expansion of the functionality of the CASP RLI, namely the provision of:

- situational awareness of all consumers of radar data connected to real-time CAD radar;

- SASP RLI mobility due to rapid changes in its architecture;

- quick connection of any subscribers - sources and consumers, including the existing fleet, without interruption of the combat control cycle;

- survivability of the radar radar detector in general due to the redistribution of radar data transmitted from sources to the radar users through servers that continue to function when individual sources fail, as well as maintaining the autonomy of the radar information exchange in individual troop groups in case of violation (failure) of data transmission lines between servers (computer network);

- delivery of radar data to consumers in their area of responsibility from sources connected to remote servers.

The specified technical result is achieved by the fact that in the known device, adopted as a prototype and including sources and consumers of radar data, connected at the output of the first and input-output of the second through the SHTKI with the input-output of the processing server of the radar, the COP connected to the output of this server, and KP, additional sets of radar processing servers with STCIs are introduced, which are located near each KP with subordinate sources and consumers of RRLs, and each SHTKI is connected to the telecode input-outputs of the KP and consumers and to the source output in. The radar processing servers are interconnected by high-speed communication lines through a computer network (for example, through the automated communication system GOST RV 5819-104-2008 "OACSS RF Armed Forces. General requirements for access networks"), and the inputs and outputs of all KP are interconnected by existing lines communication.

CASP RLI consists of a number of sources of radar 1 (radar and radar), consumers of radar 3, at least three KP 2 of different levels and SIS 4.

SIS 4 in the present invention consists of at least three servers 6 and the corresponding SHTKI 5 with communication lines 11 between them, a computer network KS 7 and high-speed communication lines 12 between servers 6 and KS 7. The SHTKI 5 are connected to the outputs of the sources RLI 1 and consumer inputs-outputs RLI 3 and KP 2 by communication lines 8, 9, 10, respectively.

SASP RLI works as follows.

Sources of radar information 1 issue through STUKS 5 to servers 6 all radar information as it arrives. Servers 6 process the incoming radar in accordance with the method [4]. Consumers 3 (fighter aircraft, anti-aircraft missile systems and systems) receive radar information on request, previously informing servers 6 what information they would like to receive - by area of space, by type of targets, etc. The specified information exchange occurs through STCI 5, which carries out coordination of protocols for the exchange of sources and consumers of radar data and the SIS protocol.

If servers 6 do not have the requested information, they receive it from the computer network 7 from other servers and give it out to consumers 3 using the matrix construction of coordinates of airborne objects and the principles set forth, for example, in [6]. This significantly reduces the time of delivery of radar data to consumers 3 due to the application on servers 6 of the “Method for processing radar data in the network information structure of an automated control system” described in [4].

Information about the current air situation is published on servers 6 for delivery to all interested consumers (including other servers) in real time, i.e. implements the principle of situational awareness.

SHTKI 5 converts the radar information received from servers 6 after processing, in accordance with the applications and protocols accepted from consumers 3, without waiting for verification and decision making on KP 2.

After checking and, possibly, changing the data on the air situation at KP 2, these changes will be reflected in the workplaces of connected users and also published on the network.

KP 2 perform the following functions:

- ensuring the display of radar data on the air situation for officials of command posts having the ability to influence radar data and sources of radar data in accordance with their authority;

- transfer of the impact of KP officials on the radar information system through the appropriate server to the relevant sources and consumers connected to the radar information security system. In this case, the existing structure of the TSA RLI is not violated, since the interaction of the KP and their hierarchy are not violated. existing communication lines 13 are not violated, and information exchange between them is not violated;

- control over the operation of servers and management of server modes.

Thus, an introduction to a known device (prototype) containing sources and consumers of radar data, connected via SHTKI with a server for processing radar data, as well as KS and KP, additional sets of servers with SHTKI connected to other KP with connected sources and consumers of radar data, high-speed lines communication between servers receiving radar data from sources as it arrives and issuing radar data to consumers at their request, as well as to any users connected to the proposed device, expands the functionality of the radar radar detector: significantly reduces the delivery time of radar data from sources to consumers, implements the principle of situational awareness for all departments that have access to the network, increases the survivability and mobility of TSA radar information systems. At the same time, the existing hierarchical management system is not violated, allowing KP officials to influence the radar data in accordance with their powers.
