Referring to FIG. 3, FIG. 3 shows functions and operation flow of the threat signal simulation module 200 among the simulation modules 200 to 400 shown in FIG. First, an administrator selects and inputs a RADAR signal, an IFF signal, and a TACAN signal as target signals, and generates and stores a threat signal by selecting or inputting a signal specification corresponding to each target signal.

The signal source simulation of the RADAR signal is composed of a frequency shape simulation (201), a PRI shape simulation (202), a scan shape simulation (203), and a pulse shape modulation simulation (204). At this time, the frequency type simulator 201 can simulate the threat signal in consideration of the operating frequency value, the modulation type, the modulation period, the modulation stage, the frequency change rate, and the other signal simulations 202 to 204, You can use commonly used input parameters to distinguish the signals.

The signal specifications of the IFF signal can be simulated according to the mode selection (211), the PTI type simulation (212), and the mode selected from Mode 1, Mode 2, Mode 3 / A, Mode 4, Mode C and Mode S There is a squawk code (Mode 1, 2, 3 / A, C) simulation 213 and a format number (Mode S) simulation 214.

In addition, there may be a channel type (X or Y) selection 221, a channel number (frequency) selection 222, and a PTI type simulation 223 as a signal source simulation of the TACAN signal.

Meanwhile, the radiated signal strength simulation (231) is also performed in the simulation of the signal characteristics of the RADAR, IFF, and TACAN signals. Although FIG. 3 shows that the radiated signal strength simulation 231 is sequentially performed after the signal source simulation of the RADAR, IFF, and TACAN signals described above, in another example, the simulation of the signal source and the simulation 231 of the radiated signal strength They may be performed concurrently or in a different order.

Such simulated threat signals can be stored / managed 232, respectively. The stored threat signal is loaded and used by the threat data generation module 500.

FIG. 4 is a diagram illustrating functions and procedures of the route simulation module in the digital threat simulation apparatus according to the present invention.

4 illustrates functions and operation procedures of the movement path simulation module 300 among the simulation modules 200 to 400 shown in FIG. In the passive location detection system, TDOA and FDOA, which are important signal sources, are extracted based on the threat and location between the receivers. To this end, the manager sequentially performs a location simulation 301, a threat location simulation 302, a threat movement path generation 303, and a threat rate simulation 304 in sequence. In addition, the simulated movement paths are respectively stored / managed (305), and thereafter, the stored movement path information can be loaded and used by the threat data generation module (500).

5 is a diagram illustrating functions and procedures of the system error simulation module in the digital threat simulation apparatus according to the present invention.

5 illustrates functions and operation procedures of the system error simulation module 400 among the simulation modules 200 to 400 shown in FIG. 2. Referring to FIG. In the system error simulation module 400, a parameter for a major error factor of the passive position detection system performance is input. Thereafter, the frequency estimation error simulation 401, the TOA estimation error simulation 402, the TDOA estimation error simulation 403, the FDOA estimation error simulation 404, and the AOA estimation error simulation 405 ) And the received pulse drop rate simulation (step 406) are stored / managed (step 407). And, it can be loaded and used in the threat data generation module 500 similar to the above.

6 is a diagram illustrating functions and procedures of the threat data generation module in the digital threat simulation apparatus according to the present invention.

FIG. 6 shows functions and operation procedures of the threat data generation module 500 operating after the execution of the simulation modules 200 to 400 in FIG. The threat data generation module 500 performs a load operation of loading the stored threat information 501, the movement path information 502 and the system error information 503 through the operation result of the simulation modules 200 to 400, And then PDW (Pulse Description Word) data, which is digital information, is generated based on the edited and edited information (504).

On the other hand, according to the request of the manager, I / Q signal generation 505 and AET (Active Emitter Table) generation 506 can be performed when necessary. That is, the I / Q signal generation 505 and the active emitter table (AET) generation 506 may not be an essential operation process in the threat data generation module 500.

In addition, the threat data generation module 500 can simultaneously generate a single threat data or a plurality of threat data using single information or a plurality of pieces of information by matching the set travel path and the threat. In addition, since the threat data generation module 500 includes a management function for the same threat of the generated AET, the set system error may be reflected by the probabilistic distribution of set values at the time of PDW and I / Q generation.

Next, FIG. 7 is an exemplary flowchart of a receiver performance test using a receiver test module in the digital threat simulation apparatus according to the present invention.

FIG. 7 shows a receiver test flow chart using the receiver test module 600 of the test modules 600-800 shown in FIG. First, a digital threat simulation apparatus according to the present invention and a receiver 1000, which is an external device, are connected to each other through a communication port 900 so as to enable data communication. Then, the manager implements the threat signal simulation, the movement path simulation, and the system error simulation through the simulation modules 200 to 400 described above. Specifically, under the control of the situation display module 100, the threat signal simulation module 200 generates a threat on the basis of the type of the target signal and the signal specification, and the movement path simulation module 300 detects the position of the receiver, , Path, and speed, and the system error simulation module generates system error information. Thereafter, the threat data generation module 500 loads threat information, route information, and system error information to complete the environment setting of the electronic electric field to be simulated.

On the other hand, the receiver test of the passive position detection system can largely be classified into the message interlocking test with the processor and the performance test of the receiver itself. In order to test the message interworking, if the user sets a message to be tested and issues a transmission command, the receiver test module 600 generates a test message and transmits the message to the receiver 1000. The receiver 1000 processes the internal operation by checking the received message and transmits a message transmission / reception history to the status display module 100 through the receiver test module 600 when a response to the message is transmitted to the digital threat simulation device The test results can be confirmed.

On the other hand, the receiver's own performance test is a test that confirms the ability to identify and detect threats by receiving digital threat data (PDW, I / Q) of received threat signals. To this end, the receiver test module 600 of the digital threat simulation apparatus according to the present invention should serve as a processor and provide digital threat data (PDW, I / Q) of simulated threat. Specifically, when the manager sets the search band in the status display module 100 and transmits a command, the manager generates search band information in the receiver test module 600, . Then, when the threat data generation module 500 requests the threat data generation module 500 to generate threat data, the threat data generation module 500 generates one or a plurality of digital threat data PDW and I / Q using the preset simulation information, Test module 600, and transmits it to the receiver 1000 through data communication.

Accordingly, the receiver 1000 performs threat signal identification / detection using the received digital threat data (PDW, I / Q) information to generate an AET for each threat. Then, the identified threat data (AET, PDW, I / Q) including the result is transmitted to the receiver test module 600. Once this is done, the administrator can check the test results in the status display module through the history of sending and receiving messages. For example, the test results can be output as a two-dimensional or three-dimensional graph through a screen or the like.

8 is an exemplary flowchart of a processor performance test using a processor test module in the digital threat simulation apparatus according to the present invention.

Specifically, FIG. 8 shows a processor test flow chart using the processor test module 700 of the test modules 600-800 shown in FIG. Similar to the receiver test of FIG. 7, the digital threat simulation apparatus according to the present invention and the processor 1000, which is an external apparatus, are connected to each other through a communication port 900 so as to enable data communication. Then, the manager performs the threat signal simulation, the movement path simulation, and the system error simulation through the simulation modules 200 to 400 under the control of the situation display module 700, and then the threat data generation module 500 And loads the information to complete the configuration of the electronic electric field to be simulated.

The handler test of the passive position detection system can be divided into the message interlocking test with the receiver and the performance test of the processor itself. To this end, the digital threat simulation device should act as a receiver in the context of the processor 1000.

In order to test the message interworking, the processor 1000 transmits a message to be tested to the digital threat simulation apparatus, and the processor test module 700 receives and transmits a response to the test message. The result of this can be confirmed through the message transmission / reception history of the processor 1000 or the status display module 100.

In order to test the performance of the processor itself, when the processor 1000 transmits the search band information and the acquisition start command to the digital threat simulation apparatus, the processor test module 700 generates threat data corresponding to the search band to the threat data generation module 500). The threat data generation module 500 generates threat data (AET, PDW, I / Q) including the threat digital threat data (PDW, I / Q) and AET for each threat, And transmits it to the processor 1000 using communication. Thereafter, the processor 1000 estimates / extracts TDOA and FDOA based on the signal cause TOA, FOA I / Q, and phase values included in the received threat data (AET, PDW, I / Q) Detection is performed. The location detection result can be confirmed in the processor 1000, and the message transmission / reception history can be confirmed in the status display module 100.

Finally, FIG. 9 is an exemplary flowchart of an integrated performance test using the integrated test module in the digital threat simulation apparatus according to the present invention.

Specifically, FIG. 9 shows an integrated performance test flow chart using the integrated test module 800 among the test modules 600 to 800 shown in FIG. For the integrated performance test, a plurality of receivers and processors must be connected to the external device 1000 using the communication port 900 of the digital threat simulation apparatus. The passive location detection system is a system that receives the threatening radiation signal from the receiver and transmits the threat data (AET, PDW, I / Q) of each threat to the processor and performs the position detection based on the transmitted threat data.

In particular, the integrated performance test described in FIG. 9 means testing the performance after the receiving end of the receiver. To this end, the integrated test module 800 of the digital threat simulation apparatus serves as a receiver of a receiver for generating digital threat data (PDW, I / Q) information. First, a user simulates a threat signal, a moving route simulation, and a system error through the simulation modules 200 to 400, loads the threat signal in the threat data generation module 500, and finishes the environment setting of the electronic electric field to be simulated.

For the integrated performance test, we set the search band in the processor and simultaneously send the acquisition start command along with the search band information to the receiver and the digital threat simulation device. After that, the receiver transmits a collection start response to the transmitter, and the integration test module 800 of the digital threat simulation apparatus transmits the threat digital threat data PDW corresponding to the search band information received by the threat data generation module 500, I / Q). When the threat data generation module 500 finishes generating the digital threat data (PDW, I / Q), it transmits it to the receiver through the integration test module 800. The receiver generates AET for each threat by performing threat signal identification / detection based on the received digital threat data (PDW, I / Q), and outputs the identified threat data including AET, PDW, I / Q ) To the processor. Then, the processor estimates / extracts TDOA, FDOA, etc. based on the signal cause TOA, FOA I / Q, and phase value included in the threat data (AET, PDW, I / . The location detection result can be confirmed in the processor, and the message transmission / reception history can be confirmed in the status display module 100.

7 to 9, the performance test method using the test modules 600 to 800 of the digital threat simulation apparatus has been described as an example. The performance test method using the ICD (Interface Control Document) of the system to be implemented The configuration or operation flow may be changed depending on the environment. Or, the specific performance test method using the test modules 600 to 800 may be changed depending on the difference in functions and roles of the receiver and the processor.

As described above, according to the digital threat simulation apparatus and method for an electronic electric field environment according to an embodiment of the present invention, prior to the performance test using actual radiation signals, By performing accurate and effective testing through various electronic field environment simulations of interlocking / functioning performance, it provides precise and effective development of the position detection system and shortens development time. Also, in the present invention, since the target signal includes not only a RADAR signal but also various signal specifications such as an IFF signal and a TACAN signal, it is possible to perform a more accurate simulation on the actual electronic field environment. Furthermore, it can be utilized not only in the electronic warfare environment, but also in civilian fields such as air traffic control systems.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, And may be modified, changed, or improved in various forms. Further, the method according to the present invention described herein can be implemented in software, hardware, or a combination thereof.
