The voice radio in the air-to-air communication, that is, the UHF (Ultra High Frequency)/VHF (Very High Frequency) band, is a survival voice exchange radio that is basically installed on all manned aircraft such as fighters and reconnaissance aircraft. As the number of built-in voice radios increased, other than voice communication, plans to use it became an issue, and from the 1990s, data link equipment using radios called IDM (Improved Data Modem) was developed.

However, due to the deterioration of the frequency hopping performance of RF (Radio Frequency) and the analog data interworking interface, the conventional radio could be operated in the fixed frequency mode instead of the hopping mode for tactical digital data distribution, and the transmission speed was also lower than that of the analog (voice) band. was not as high as the limit.

SATURN radio is a radio with a new waveform and frequency hopping algorithm applied in the 2010s, and RF performance is improved and an interface for digital data distribution has been added. If a tactical data link subsystem that can be applied (utilized) to these radios is developed, it is expected that a small amount of tactical data link data can be distributed by utilizing the non-operating time of voice distribution while operating the public voice radio.

1 is a diagram for explaining an IDM-based tactical data link network using a voice radio.

In general, an IDM system using a voice radio to which HaveQuick is applied can theoretically distribute a tactical data link of 16kbps or less in a fixed frequency operation mode. When constructing an IDM-based tactical data link network, development factors are increased due to three constraint factors, but on the other hand, it is possible to build a small capacity tactical data link network in a poor environment.

Voice radio (UHF/VHF public communication frequency band) is largely installed and operated for voice communication in a fixed central station, at least one subscription node, and a Tactical Air Control Party (TACP) platform. In addition, IDM can distribute tactical data through the voice radio at a desired time by connecting the analog data interface of each voice radio and PTT (Push To Talk).

To establish a tactical data link network, the fixed central station must transmit IEN information for acquiring TDMA reference synchronization to each node, and each network node can join the network using the received IEN information.

The problems of such a tactical data link network can be largely identified into three types.

First, when performing tactical data link operations in a fixed central station, IEN information must be created and shared with each node. To use the HaveQuick mode, it is necessary to initialize to TOD (Time of Day), but since the HaveQuick mode of the radio is not used in the fixed central station, the TOD information applied to the radio cannot be used. In addition, depending on the radio performance, the subscription node wastes unnecessary time to acquire IEN information of the fixed central station, so there is a problem in that it is impossible to quickly establish a network.

Second, when a voice radio operated in a fixed frequency mode is used as a tactical data link RF system, it is impossible to utilize a unique voice radio.

Finally, the analog data path stabilization time is required during transmission and reception due to the deterioration of the RF performance of the voice transceiver. In case of transmission, Attack Time and AGC (Automation Gain Control) time at reception are required to be more than several hundred ms. In addition, TDMA network slot allocation becomes possible by utilizing pure data transmission time considering all time.

An embodiment of the present invention aims to improve the performance of a voice radio system in which performance deterioration of existing voice radios, unnecessary time consumption for acquiring tactical data link network synchronization, and simultaneous operation of tactical data distribution are impossible.

At this time, the SATURN radio with improved performance is characterized by applying a new waveform and frequency hopping system. The SATURN radio in an embodiment of the present invention operates on a UHF (225-4000 MHz) voice communication-only frequency, and the RF delay time during transmission and reception is also improved. In addition, a digital interface that enables digital data service interworking with the existing analog data service is also provided.

According to the known communication tactical data link system (or KID; Korea Improved Datalink) utilizing the SATURN radio according to an embodiment of the present invention, it is possible to obtain automatic synchronization and slot assignment, and to simultaneously operate a voice radio. It is possible to build a small-capacity tactical data link network using the voice radio frequency band.

Hereinafter, a SATURN radio-based public communication tactical data link system 100 (hereinafter, a public communication tactical data link system) according to an embodiment of the present invention will be described with reference to FIGS. 2 to 6 .

2 is a block diagram of a known communication tactical data link system 100 according to an embodiment of the present invention. FIG. 3 is a view for explaining the UHF RF frequency signal recognition unit 110 . 4 is a diagram for explaining the modem timing generator 120 . FIG. 5 is a diagram for explaining the transmission slot information generation unit 130 and the transmission unit 140 .

The known communication tactical data link system 100 according to an embodiment of the present invention includes a UHF RF frequency signal recognition unit 110 , a modem timing generation unit 120 , a transmission slot information generation unit 130 , and a transmission unit 140 . include

At this time, the SATURN radio based on the present invention is the latest version of the public communication radio for exchanging voice information, and the public communication radio includes an analog port for exchanging voice and a digital port for data communication service. In this SATURN radio, frequency hopping timing is determined during voice transmission/reception based on pre-applied TOD information. And the known communication tactical data link system 100 according to the present invention is connected to the RF signal interface, PTT and digital data distribution interface of the SATURN radio.

The known communication tactical data link system 100 according to the present invention is operated after various initial settings are stored before operation.

For example, the public communication tactical data link system 100 stores a variety of PSK (Phase Shift Keying) modulation/demodulation waveforms with a pulse length of at least 21us before operation, and then selects applicable waveforms based on the generated timing information. You can choose to apply it.

In addition, the known communication tactical data link system 100 is equipped with each known communication tactical data link system 100 before operation, and the number of all nodes constructed as a tactical data link network is input. In this case, the node may be divided into one master node and N (N is a natural number) number of slave nodes. In addition, the transmission order between the slave nodes is set to be assigned sequentially.

First, as the power of the known communication tactical data link system 100 is applied, the UHF RF frequency signal recognition unit 110 recognizes the UHF RF frequency signal transmitted from the SATURN radio.

Referring to FIG. 3 , the UHF RF frequency signal recognition unit 110 includes a plurality of RF filter units, a single conversion unit, an ADC unit, and a frequency occupation time recognition unit.

The plurality of RF filter units are configured to have a predefined frequency band in order to recognize the RF signal of the UHF band. In an embodiment, the plurality of RF filter units may filter a frequency signal of a 44 MHz band, and may include first to fourth RF filter units. A plurality of RF filter units may filter a predefined frequency band, the first RF filter unit 225-269 MHz frequency band, the second RF filter unit 270-314 MHz frequency band, the third RF filter unit 315-359 MHz frequency band, 4 The RF filter unit can filter the frequency band of 360 ~ 400MHz.

The single conversion performing unit single-converts the filtered signal by dividing it into a predefined frequency band, and the ADC unit converts the single-converted signal into a digital signal.

The frequency occupation time recognition unit recognizes the frequency occupation time for the UHF RF frequency signal by processing the converted digital signal with FFT and channeling signals. In this case, the recognized frequency occupation time may be shared with the TOD-approved radio. That is, the frequency occupancy time recognized by the frequency occupancy time recognition unit is secured equally for all SATURN radios to which the TOD is applied.

Next, the modem timing generating unit 120 generates timing information for tactical data link network operation based on the recognition result of the UHF RF frequency signal.

Referring to FIG. 4 , the modem timing generator 120 generates timing information usable in a tactical data link network based on an occupancy index corresponding to a signal of a 225 to 400 MHz UHF band.

The modem timing generating unit 120 generates timing information including a recognized section determined through accumulated signal processing a preset number of times and an unoccupied section that is a section other than the recognized section. As an example, the recognition period is determined by cumulative signal processing three or more times through a counter, and needs to be accumulated three or more times in consideration of the collision of the received signals. When the recognition section is confirmed, the remaining sections except for the confirmed recognition section become unoccupied sections, and the time of the periodic unoccupied section is determined.

At this time, the first node using the voice radio among the plurality of nodes is automatically set as the master node, and the remaining nodes are set as the slave nodes. The master node generates IEN information and transmits it to a plurality of slave nodes, which will be described later.

Next, the transmission slot information generation unit 130 generates transmission slot information based on the generated timing information, and the transmission unit 140 transmits the IEN information by using the transmission slot information.

Referring to FIG. 5 , the transmission slot information generating unit 130 secures slots available in the tactical data link network based on the timing information generated by the modem timing generating unit 120 . The secured slot has a certain occupancy time, and the transmission slot information generating unit 130 utilizes information such as the pulse time of a pre-implemented waveform and the number of pre-inputted expected nodes through the secured occupancy time to obtain tactical data. You can select a waveform applicable to the link network.

The transmitter 140 generates IEN information based on a preset time for the tactical data link network and allocates it to the transmission slot information. In this case, the preset time may be 12 seconds. In addition, the transmitter 140 may generate reference data for determining the number of occupancy between nodes according to the previously input number of nodes, allocate them to slots, and then transmit the data.

In one embodiment, the transmitter 140 calculates the transmittable data rate based on 12 seconds, and broadcasts the IEN information, the inter-node reference signal, and the allocation information to each node by 1/N with the initially input number of nodes. have.

6 is a diagram for explaining the contents of data transmission based on timing information.

The known communication tactical data link system 100 according to an embodiment of the present invention determines a time for using the SATURN radio as RF based on the generated timing information. That is, the generated timing information is applied as a PTT to the SATURN radio when transmitting data.

The transmission slot information generating unit 130 of the known communication tactical data link system 100 may select an applicable waveform based on the timing information.

Specifically, the transmission slot information generator 130 sets the network available time of a first stack among a plurality of stacks corresponding to a network available time (NAT) included in the timing information, a constant determined based on the frequency hopping time. It is possible to select and apply a waveform having the closest transmit pulse timing to the result of dividing by . For example, the transmission slot information generating unit 130 may select and apply a waveform having the transmission pulse timing closest to the result of “STACK 1 timing/3” in FIG. 6 . At this time, the constant 3 is derived by analyzing the frequency hopping time in the SATURN radio in advance.

When the sum of all N stacks among a plurality of stacks corresponding to the network availability time included in the timing information is equal to or greater than a predetermined time, the transmitter 140 may start transmission from a timing corresponding to the next network availability time. For example, when the sum of all network availability times from STACK 1 to STACK N is 12 seconds or more, the transmitter 140 may start transmission from the next NAT timing.

In this case, one stack is occupied so that only nodes designated in a predetermined number can transmit, and an example of the predetermined number may be three nodes.

As described above, in the known communication tactical data link system 100 provided in a plurality of nodes, a node using the first voice radio among the plurality of nodes is designated as a master node, and the remaining nodes are designated as slave nodes, from the master node. All slave nodes receiving the IEN information determine the starting point for establishing the tactical data link network based on the IEN information. In addition, in the initial setting of the known communication tactical data link system 100, the transmission order for the slave nodes is set, and each node can transmit by occupying the stack according to the allocation priority compared to the initially set total number of nodes.

On the other hand, when the transmission timing of the total number of nodes is less than the time corresponding to M stacks (M<N, M being a natural number), the transmitter 140 of each node transmits from the M stacks to the N stacks in the same period. can do.
