Description

Electronic warfare signal low data generation device for avionics electronic warfare system and method of generating low data

The present invention relates to a row data generation apparatus capable of generating row data corresponding to an electronic warfare threat signal in an avionic warfare system supporting an avionic warfare, and a method of generating the raw data thereof.

In recent wars, it is recognized that electronic warfare is very important for war victory or effective defense system.

Such electronic warfare may be subdivided into electronic attacks, electronic protection, or electronic support, depending on its characteristics.

 For example, the electronic attack (EA) is characterized by the use of electromagnetic waves to disable the other electronic equipment, the electronic protection (EP) is characterized by all activities performed to protect their electronic equipment from the opponent's electronic attack. In addition, the electronic support (ES) is characterized by recognizing the threat (threat) by collecting and analyzing the electromagnetic spectrum energy of the opponent, further supporting electronic warfare activities through the location analysis of the threat, signal analysis and eavesdropping.

However, in the state of the art weapon systems that attack or defend against opponents, even if electronic warfare is an essential item that must be applied, hundreds to hundreds of billions of dollars are required to develop or introduce electronic warfare systems. If you buy a fighter plane, the cost burden is bound to rise to the astronomical level.

Therefore, it is necessary to fully verify in advance the utility of the electronic warfare system to be developed or introduced to prevent national waste.

To this end, national costs should be prevented by targeting and simulating attacks and defenses or verifying their effectiveness by direct demonstration.

While the targets of attack and defense are clear and the effectiveness of simple electronic attacks or electronic protection systems is easily verified by simulations or demonstrations, the simulation of avionics systems is very difficult for a variety of reasons. In avionics systems, there are many threats, the influence of electromagnetic wave propagation paths and terrain is very large, and this is due to a variety of reasons, such as indefinite when electromagnetic waves will be used.

2 is a conceptual diagram illustrating a method of interlocking a scenario management module and a row data generating device.

Referring to FIG. 2, the avionics warfare system includes a scenario management module and a raw data generator.

The scenario management module functions to model signal transmitters, signal receivers, aircrafts, etc. constituting avionic warfare, generate simulations, and manage scenarios.

The raw data generating device generates a data on the threat signal by using the information on the enemy threat signal simulated by the scenario management module and transmits the data on the threat signal to the control panel and the storage device.

The raw data generator receives threat data using the scenario management module and the TCP connection.

The scenario management module works as a TCP server and the raw data generator as a TCP client.

The raw data generator receives initial threat information and changed threat information as a simulation result from the scenario management module and generates corresponding raw data.

COMINT generates threat information including the COMINT threat name, threat frequency, and reception strength, as well as detection information including the threat name, reception strength, detection angle, and line of sight.

ELINT generates threat information including ELINT threat frequency and reception strength. ELINT (Electronic Intelligence) is electronic information obtained by collecting and analyzing the characteristics of electromagnetic waves from nuclear explosions or electromagnetic radiation.

3 is a block diagram illustrating the components of a row data generating apparatus.

The row data generating device includes a presentation layer, a business layer, and a data layer.

 In the presentation layer, the control panel of COMINT, ELINT, and FISINT, the TCP connection view showing the TCP connection status, the UDP connection view, the operation parameter setting view for setting the transmission file or the reference file for generating the raw data, and the raw data generator and control panel Includes a transport traffic view that represents the status of intercom / receive messages.

The TCP connection view shows the TCP connection status between the raw data generator and the COMINT and FISINT control panels for COMINT and FISINT. For example, it can show the name, IP address, and TCP connection status of the raw data generator. It also includes the names of all devices connected to COMINT and FISINT, and the ip addresses of all devices connected to COMINT and FISINT.

The UDP connection view shows the UDP port open status for UDP communication with the ELINT control panel (including LANtoVME) and the raw data generator in ELINT. For example, names of all devices connected to ELIENT, ip addresses of all devices connected to ELIENT, and UDP open status for each device may be represented by the UDP connection view.

The raw data generator generates simulation data such as demodulation, voice, and I / Q by referring to the information stored in the file. Therefore, it provides a reference file designation function for data generation and a function for setting a transmission cycle to the control panel and other information for data generation.

The business layer performs the function of generating raw data.

The business layer receives the data generation request value (or operating parameter) from the control panel and generates the raw data correspondingly. In this case, the business layer may search for threat information linked from the scenario management module and generate row data in different ways according to the search result.

Furthermore, the business layer manages TCP / UDP network connections and receives operational parameters for receiving and processing messages from the COMINT, FISINT, and ELINT control panels for each simulated device.

The business layer performs a timer function that allows the timer to call the data generation function according to the registration cycle and transmit the generated data to the control panel after registering the data generation cycle with the timer.

When the raw data generator receives the parameters from the control panel, the raw data generator periodically generates and transmits data to the control panel until spectrum or demodulated data is received from the control panel. Therefore, after the data generation cycle is registered with the timer, the timer can call the data generation function by the registration cycle and transmit the generated data to the control panel.

The data layer manages threat information about COMINT, FISINT, and ELIENT in the scenario management module in memory. The data layer manages the messages received from the control panel in memory and then manages the operating parameters required to generate data based on this information.

The data layer manages mock data such as demodulation, voice, I / Q, etc. into a file and performs a row data file management function to refer to the contents of the file when generating data. Furthermore, traffic status information for managing data transmission / reception amounts is managed to monitor transmission / reception message traffic conditions between the raw data generator and the control panel.

FIG. 4 is a conceptual diagram illustrating a method of generating row data by the row data generator of FIG. 3.

The raw data generator receives the data generation request value (or an operating parameter) from the control panel and stores it in the memory.

The raw data generator distinguishes between data that needs to be generated only once or data that needs to be generated periodically based on operating parameters received from the control panel. In the case of data that needs to be generated periodically, a schedule can be registered in a timer to periodically generate low data.

The timer may determine a row data generation period based on the operation parameter. At this time, the generation period is adjusted to be lower than the minimum generation period. This is to prevent the system load caused by the generation of frequent raw data. For example, the minimum generation period may be 1/1000 sec.

The raw data generator retrieves the threat information linked from the scenario management module. Depending on the search result, raw data is generated in different ways.

For example, if there is threat information, the raw data is generated in the first manner by applying the threat information, and when there is no threat information, the raw data is generated in a second manner different from the first method.

The raw data generator receives threat information from the scenario management module. The threat information may include at least one of frequency, received power, detection angle, detection error, threat location, and signal strength.

5 is a conceptual diagram illustrating a method in which a raw data generating apparatus processes a large amount of data.

 When designing a device to generate simulated threat signals in avionics warfare, it is necessary to consider a massive amount of data processing that is congested as in a practical environment.

The row data generator generates row data as in a practical environment. When a large amount of data is generated, the raw data generating device controls the traffic by adjusting the amount of data transmitted to the control panel. For example, the row data generator monitors the amount of row data generated during a unit time. If the row data amount satisfies the first condition, the row data generated during the first reference time is included in one transmission queue and transmitted. If the row data amount satisfies the second condition, the row data generated during the second reference time is included in one transmission queue and transmitted. In conclusion, the amount of row data included in one transmission queue varies according to the amount of row data generated during a unit time.

The row data generating apparatus may change a predetermined generation period of the row data when a larger amount of data than the reference occurs for a unit time. For example, the generation period may gradually decrease according to the amount of data generated. In a state in which the row data is determined to be set every 10 seconds, when the generated row data is larger than the reference, the generation period may be changed from 10 seconds to 20 seconds.

When the generation period of the specific row data becomes slower than the maximum period (for example, when the generation period becomes two minutes while the maximum period is set to one minute), the row data generator deletes the generation period of the specific row data. Can be. In this case, generation of specific row data is stopped.

Even if the control panel commands generation of specific row data at regular intervals, when the amount of generated data exceeds the standard, the row data generator may adjust the system overload by adjusting the generation period. Furthermore, the generation of specific row data itself may be stopped.

6 is an exemplary diagram for describing a user interface provided by a row data generating apparatus.

The raw data generating apparatus according to the present invention provides a menu for selecting COMINT, ELINT, and FISINT.

The raw data generator provides a menu for starting and ending. In case of start, open TCP port open for COMINT and ELINT, UDP port number for ELINT, and initialize the resources. Initialization of a resource refers to a task of initializing a file reference information for generating raw data and a data generation cycle. If it stops, it closes TCP and UDP ports at start and releases the resources.

In case of COMINT and FISINT, the control panel and TCP connection status are represented. It is shown as blue when session is connected and red when session is off.

In case of ELINT, UDP port is open. It shows blue when open is successful and red icon when open fails.

The raw data generator can show the data transmission / reception status between COMINT and FISINT and the control panel, and the data transmission / reception status between ELIN) and the control panel (including LANtoVME).

Furthermore, the row data generator may provide a window for setting a file and other parameters required for operation that the row data generator refers to when generating data. At least one of operation parameters and threat information used to generate the raw data may be displayed on a display.

The present invention can be embodied as computer readable codes on a medium on which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like. This also includes implementations in the form of carrier waves (eg, transmission over the Internet). The computer may also include a terminal.

Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
