Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.
Existing systems that identify threats by analyzing various threat signals that occur on the battlefield and send jamming to identified threats can be used to identify unidentified threats (eg, new threats not defined, threats not stored in the library, etc.) Jamming can not be done.
In order to develop a jamming algorithm for unidentified threats, it is necessary to develop a device that simulates the success of jamming by receiving and analyzing jamming signals through generation and transmission of unknown signals. Hereinafter, an apparatus for developing an optimized jamming algorithm for unknown signals will be described.
1 is a reference diagram for explaining the operation principle of a jamming signal processing system according to an embodiment of the present invention.
The conventional threat signal generating apparatus generates a threat signal based on the information stored in the library and does not have a function of stopping the radar generation by analyzing the jamming signal. That is, the conventional threat signal generating apparatus has a problem that it can not determine whether or not the jamming is successful by transmitting and generating a threat signal, and receiving and analyzing the jamming signal. In order to determine the jamming success of the unknown signal, it is necessary to verify the algorithm through the corresponding device.
The jamming signal processing system proposed in the present invention is operated in the following order to solve the above-mentioned problem.
First, the jamming signal processing system generates a threat signal based on the information stored in the library (S110).
Thereafter, the jamming signal processing system transmits the threat signal to the outside (S120).
Thereafter, the jamming signal processing system receives and analyzes the jamming signal for the threat signal (S130).
Thereafter, the jamming signal processing system determines whether or not the jamming signal is normally generated by the jamming signal generator based on the result of analyzing the jamming signal (S140).
If it is determined that the jamming signal has been normally generated, the jamming signal processing system stops external transmission of the threat signal (S150).
Next, an operation method of the jamming signal processing system will be described. 2 is a flowchart schematically illustrating a method of operating a jamming signal processing system according to an embodiment of the present invention.
First, the jamming signal processing system generates a jamming signal and transmits it to a jamming signal generator equipped with an algorithm for generating a jamming signal (S210). The jamming signal processing system can generate the unknown signal by generating frequency, PW, PRI and the like through the radar generator arbitrarily. Since the signal generated by the jamming signal processing system is an arbitrary component, the system receiving the signal receives it as the unknown signal.
Thereafter, the jamming signal processing system receives the jamming signal for the unknown signal from the jamming signal generator and analyzes the jamming signal (S220).
Thereafter, the jamming signal processing system compares the result obtained by analyzing the jamming signal with the information used when the jamming signal generator generates the jamming signal (S230), and verifies whether or not the jamming signal is normally generated by the jamming signal generator (S240) .
In the above, the jamming signal processing system can analyze the jamming signal and calculate the jamming technique as a result. In addition, the jamming signal processing system can previously store the information used in generating the jamming signal in the library of the database in order to determine whether or not the jamming signal has been normally generated.
The jamming signal processing system determines that the jamming signal is normally generated by the jamming signal generator when it is determined in step S240 that the jamming technique obtained as a result of the analysis matches the one stored in the library. On the other hand, if the jamming signal processing system determines that the jamming technique does not match the one stored in the library, it determines that the jamming signal is not generated normally by the jamming signal generator.
If it is determined that the jamming signal is normally generated, the jamming signal processing system controls the threat signal to no longer be output (S250). On the other hand, if it is determined that the jamming signal has not been normally generated, the jamming signal processing system controls the threat signal to be output again.
The jamming signal processing system according to the present invention is an apparatus for developing an algorithm for generating an optimized jamming library for a known signal, and generates and transmits a unknown signal, receives a jamming signal of the system to which the algorithm is applied, And confirm the jamming success / failure.
The jamming signal processing system generates the unknown signal and stores the jamming signal for the transmitted signal in the library during transmission. The jamming signal analysis is used to compare the jamming signal with the library, Stop. The optimization algorithm can determine that the threat signal is stopped and store the signal and the jamming specification in the library.
The jamming signal processing system according to the present invention can verify the algorithm for generating the optimized jamming library for the unknown signal through the above-described operation, and can perform the break-lock simulation through the jamming signal analysis.
Since the existing threat signal generator / generator is generated by generating the signal specified in the library, it does not receive the signal generated from the target device. Therefore, the jamming signal is analyzed using a separate receiver without analyzing / discriminating.
However, the apparatus proposed in the present invention (i.e., an apparatus for developing an algorithm for generating an optimized jamming library for the unknown signal) generates a threat signal and receives a jamming signal generated in the target apparatus, Therefore, it is not necessary to use a separate receiving device, analyzes the received signal in order to simulate the break-lock of the actual radar, and if it matches with the predetermined library, it determines that it is break-lock and stops generating the threat signal .
The existing system can not judge whether or not the jamming has succeeded. It is necessary to use the actual radar to determine whether the vehicle is in a break-lock state. In order to verify the algorithm using the radar, . The present invention solves this problem, and algorithm verification using the present apparatus is possible through a predetermined library.

On the other hand, the jamming
In the present invention, the jamming
The operation principle of the existing jamming system will be described as follows. 4 is a reference diagram for explaining the operation principle of a conventional jamming system.
In the conventional jamming system, when a threat signal is received (S405), the threat signal is analyzed based on the library (S410).
Then, if the threat signal is identified (S415), the conventional jamming system applies the jamming technique (S420) and transmits the jamming signal to the outside (S425). The conventional jamming system can improve the survival rate of the system put into the battlefield by transmitting the jamming signal against the identified threat (S430).
On the other hand, in the conventional jamming system, if the threat signal is not identified (S435), it is impossible to find an appropriate jamming technique and it becomes impossible to transmit the jamming signal to the outside (S440). In the conventional jamming system, since the jamming transmission is impossible with respect to the unidentified threat, the survival rate of the system put into the whole field may be reduced (S445).
The present invention has been proposed in order to overcome the disadvantages of the conventional jamming system. When the unidentified threat is received, various jamming signals are transmitted to find an optimized jamming technique by checking a break-lock, And transmits the optimized jamming signal to a non-identified signal received thereafter to improve the survivability.
Hereinafter, the system proposed above will be described with reference to FIGS. 5 and 6. FIG. The proposed system adopts an algorithm for generating an optimized jamming library for an unknown signal.
5 is a flowchart illustrating an operation method of a jamming signal processing system according to another embodiment of the present invention. And FIG. 6 is a reference diagram for explaining a process of generating a jamming signal by the jamming signal processing system according to an embodiment of the present invention.
First, an operation method of the jamming signal processing system will be described with reference to FIG. Each configuration of the jamming
When the unknown signal is received by the signal receiving unit 313 (S505), the
Thereafter, the
If it is determined that the unknown signal is identifiable, the jamming technique application / generation unit 315 detects an optimized jamming technique for the identified unknown signal based on the information stored in the library 314 (S520).
Thereafter, the jamming technique application / generation unit 315 generates a jamming signal based on the detected optimum jamming technique, and the
Thereafter, the brake lock confirmation unit (not shown) determines whether a break-lock is generated based on the signal received by the
Break-lock is a phenomenon in which a system that uses radar to detect and track a target loses its target and can no longer track the target. The jamming
If it is determined in step S530 that no break lock has been generated, the jamming technique application / generation unit 315 applies the remaining techniques except for the jamming technique previously used for generating the jamming signal among the jamming techniques stored in the library, And S525 are repeated. The jamming technique application / generation unit 315 may repeat the above process until it is determined that a brake lock is generated.
If it is determined in step S530 that the brake lock is not generated, the jamming technique application / generation unit 315 may perform steps S520 and S525 again using the same jamming technique as before.
On the other hand, if it is determined in step S530 that a break lock has occurred, the jamming
If it is determined in step S515 that the unknown signal is not identifiable, the jamming technique application / generation unit 315 generates a jamming signal by selecting the highest priority jamming technique according to the scenario to which the sequence is applied (S535).
The jamming technique application / generation unit 315 is an element necessary for developing an algorithm for generating an optimized jamming library for the unknown signal, and starts jamming by applying a predetermined sequence according to characteristics of the analyzed signals after the unknown signal analysis. In other words, the jamming technique applying / generating unit 344 analyzes the unknown signals, and if the jamming technique applying unit 344 corresponds to a similar jam based on the identified library corresponding to the corresponding jam (eg, RF band, PRI / PW, etc.) Jamming is initiated by sending a signal. At this time, the jamming signal transmitted by the jamming technique application / generation unit 344 is not an optimized jamming signal, but is useful for finding an optimized jamming technique in a short period of time because the characteristic corresponds to a similar jam.
Jamming is a technique that is not used in conventional jamming systems. It uses the frequency characteristics of the signal, PW (Pulse Width), and PRI (Pulse Repeat Interval) as variables to apply the most probable library The most optimized techniques are selected, and several scenarios to apply the order are created and charged differently according to the unknown threat signal.
In the conventional jamming system, the jamming technique generation algorithm is applied only to the identified threats, but the jamming
If the jamming signal is generated in step S535, the
Thereafter, the brake lock confirmation unit determines whether a break-lock is generated based on the signal received by the
If it is determined that the break lock is generated, the jamming technique storage unit (not shown) stores the jamming technique used for generating the jamming signal in the library together with information on the pattern of the unknown signal in step S555. Then, the jamming
In the conventional jamming system, only the determined jamming is transmitted and only one jamming is continuously transmitted irrespective of success or failure. On the other hand, the jamming
This procedure of the jamming
Even if the operation is performed in the same area, the jamming can be succeeded even if the unknown signal is inputted by using the library reflecting the sequential jamming technique according to the present invention.
The algorithm for automatically registering the library by judging optimization jamming does not apply any existing system, and the algorithm can be applied to various platforms and used.
If it is determined in step S550 that the brake lock is not generated, the jamming technique application / generation unit 315 generates a jamming signal by selecting the jamming technique of the next rank according to the scenario to which the sequence is applied (S560, S535, S540 ). This operation of the jamming technique application / generation unit 315 can be continuously repeated until it is determined that a brake lock is generated.
The operation method of the jamming signal processing system described with reference to FIG. 5 will be summarized as follows.
Development of an algorithm for generating an optimized jamming library for unknown signal is an algorithm development to find an effective jamming technique even when the received threat is not identifiable and increase the survival rate of the system through jamming transmission.
If you receive an unknown radar signal, it is impossible to identify it even if you analyze it. However, analysis of the signal can determine whether it is a search radar or a lock-on radar. According to the present invention, the PA (Pulse Amplitude) characteristic of the received signal is analyzed to determine whether it is a signal by a search radar or a signal by a lock-on radar according to the pattern.
The algorithm transmits jamming signals by sequentially applying jamming techniques in a predefined order to lock-on unknown signals.
Jamming is judged to be successful at the time when break-lock is released due to release of lock-on to the unknown signal received after sequential jamming transmission, and the applied jamming technique is stored in the library in an optimized manner.
If a signal of the same pattern is received as a result of analysis of the unknown signal, an optimized jamming technique is applied according to the stored library. When signals of different patterns are received, the jamming technique is sequentially applied again in a predefined order, .
If you store the library in the same way as above, jamming can be successful even for unknown signals in the area. The algorithm can be applied to the battlefield system, and even if the operation is performed in a new area, it can improve the survival ability and improve the operational performance. That is, the present invention complements the disadvantage of not being able to jam the unidentified signals of the existing system, thereby enhancing the survival rate of the system put into the battlefield and improving the operational performance.
Next, referring to FIG.
When a signal is generated by the radar # 1 (Radar # 1) 330, the jamming
The jamming
If no break-lock occurs for the first jamming scheme, the second jamming scheme is applied to transmit the jamming signal. In the same way, a break-lock is detected and the jamming signal is transmitted by applying the n-th jamming technique according to whether the break-lock has occurred.
The jamming
As mentioned above, n times of jamming is applied to n radars, and the optimized technique is stored in the library. If no unknown signal is received, all the unknown signals in the area are stored in the library.
The library can then be used to perform operations in the area, and the optimization algorithms can be applied to systems operating in new areas.
On the other hand, the jamming
The present invention described with reference to FIGS. 4 to 6 can find an optimized jamming scheme against an unidentified threat and enhance the survivability of a system put into the battlefield through jamming transmission.
The present invention described with reference to Figs. 1 to 6 can be applied to an electric field system (or electronic warfare system) for improving survivability, an electric field system (or an electronic warfare system) performed in a new operation area, a device for signal acquisition / Can be applied. The present invention can be used, for example, in an electronic warfare (EA) system, and it is possible to actively create a library in an area where a pre-established library can not be used, thereby improving survivability.
